How to restrict the CSS for only a particular page? - html

I was trying to insert another html page into an php page by using "include"
and that html page is having some stylesheets imported,
When I insert that page, it disturbs my PHP page..
How can I restrict the CSS for that particular page only?

place the imported page inside a container div, and then give it an id like:
<div id='included_page'> Your page goes here...</div>
Then add #included_page .someClass{mystyle: property;} to each and every style defined.i.e, increase the level.

Add a class or id to each <body> and write styles accordingly like below
HTML
<body class='home'>
Home page content
</body>
<body class='about'>
About page content
</body>
CSS
.home .someclass{
}
.about .someclass{
}

Try this.
In Page[restrict the CSS]:
<?php
$type = 'exclude';
inlcude('page_to_include.php');
page_to_include.php:
<?php
if(!isset($type) or ($type !== 'exclude')) {
// Things to be excluded from Page 1;
}
Ref: PHP - include a php file and also send query parameters

How to redirect to a particular section of a page in html

I am done with redirection to target page but what I want is to redirect to particular <div> of the page. How can this be achieved?
You can do it in two ways.
1) [via Javascript (+jQuery)]
home
$('#home').click(function(){
$(document).scrollTop(100) // any value you need
});
2) [via pure HTML]
home
<section id="home_section"></section>
<div id="go1">
<!-- content -->
</div>
<div id="go2">
<!-- content -->
</div>
<div id="go3">
<!-- content -->
</div>
...
Just append url id as below ,you are done !
news.html#go1
news.html#go2
news.html#go3
This is the easiest way for me
<li>Prices</li> (This could be a paragraph or a button)</li>
<div id="prices">
// Prices section
</div>
You need to add id attribute to that section of page you want to show and pass id name at the end of url using hash (#) symbol. For example you want to redirect user to div with id='test'
<div id="test">your section content</div>
Then you should use this url structure:
http://example.com/your_page.php?some_param=1#test
Basically you use anchor tags in HTML to get your job done.
You'l probably be familiar with them as:
As HTML convention, while defining a section, you can give each section an ID for identifiers :
<section id= "blahblah" ></section>
And you can redirect to the section by just mentioning them in the anchor tags :
You can link the html code with css.
In c#
Response.Redirect("http://www.example.com/index.aspx#id_in_css");
Here are two conditions,
1) If you want to redirect to div from different page:
Page
if(window.location.href.includes("div-panel"))
{
$(document).scrollTop(450);
}
2) If you want to redirect to div in same page:
<button id="button-click">Panel</button>
$('#button-click').click(function(){
$(document).scrollTop(450);
});
Give that section an id (lets say: section1) and then the redirect url will be http://www.sample.com/page#section1 .
Note: the # and the keyword, that's the id of the section you want your browser to scroll to.
Read more about Fragment Identifier here
If you really want that smooth sliding to the designed section, here's a quick step-by-step:
In the section you want, create an id property, i.e:
<section id="products">
next, using an anchor tag, insert # + the id for the section on the href property:
<a href="#products">
Now, once clicked, the page will center the section pointed on the anchor tag. But this will happen brutely. In order to smooth the scrolling process, in your CSS file, use this snippet:
html {
scroll-behavior: smooth;
}
And that's the simplest way!
There is also ways for doing it with native JavaScript and JQuery. For more, i recommend the article on CSS Tricks -> https://css-tricks.com/snippets/jquery/smooth-scrolling/
first you need add id where you want to redirect
<section class="com-padd com-padd-redu-top" id="deals-home">
than add
< a href="{% url 'home' %}#deals-home">Go to Home that page</a>

How to manage elements that are the same across multiple pages

Brand new to html/css, is there a way to manage recurring elements on a site such as a toolbar? For example, if I have a website with 10 pages and want to change the HTML for the universal toolbar, do I have to change it on all 10 pages?
The easiest way would be a server-side include.
Meaning, you have:
index.php
head.php
footer.php
nav.php
And in index.php you looks something like:
<?php include_once "head.php"; ?>
Actual content here
<?php include_once "footer.php"; ?>
head.php for example, would look like:
<!doctype HTML>
<html>
<head>
<title>Hello</title>
<?php include_once "nav.php"; ?>
</head>
<body>
Depends. If the HTML is written in 10 different places then Yes, you have to change it on all 10 pages.
If you're adding the HTML to all pages through a common usercontrol(if you are .net that is) or using a template, then you can do it in 1 place & be done with it.
If you mean having recurring items check out Madara's answer. If you mean recurring styles, the following will give you an example:
If you want a certain text to show up as red every time, you can name it "Red":
In css:
.red{
color: red;
}
The "." indicates its a recurring element and you can name it whatever you want as long as its being used in the html.
In html:
<span class="red">Sample text</span>
You have few options:
Use some server-side language (i.e. PHP) - recommended
Use iframe tag:
<iframe src="toolbar.html"></iframe>

How can I make my navi-bar the same across my html?

With each new page I have to update the navigation panel. Which means I go from page to page copying and pasting my navigation bar. The more pages I add the harder it gets. Now I have in-consistent navigation bars. So what I'm looking for is a way to make an html file that contains only the navigation bar, then embed it into my code, like I'd do with CSS and JavaScript. That way if I edit the one file all other pages get updated. If I use the iframe tag there would be way to many problems, but I know of no other tag that can do what I need. So what should I do? I've done some research but all I can find is the iframe tag.. What should I do?
If your page is strictly HTML+JavaScript, you can use HTML DOM innerHTML Property.
Here is an example:
index.html
<body>
<nav id="navMenu"></nav>
<div> rest of web page body here </div>
<script src="script.js"></script>
</body>
about.html
<body>
<nav id="navMenu"></nav>
<div> rest of web page body here </div>
<script src="script.js"></script>
</body>
script.js
document.getElementById("navMenu").innerHTML =
'<ul>'+
'<li>Home</li>'+
'<li>Services</li>'+
'<li>About</li>'+
'</ul>';
Important line here is nav tag, and all you need to do is to add this line in other pages in this example about.html.
I also recommend PHP or similar to accomplish what you need!
If your page is strictly HTML then you will just have to do copy and paste. It would have been a lot better if you were using may be PHP then you can simply do an include or require but as the situation is now, all you need is to do a clean HTML coding for your navigation. Indent your codes well then it will be easier for you to copy and page across all pages.
If you can use simple PHP codes then read this: http://www.w3schools.com/php/php_includes.asp
I'd strongly recommend using PHP:
<?php include "header.html"; ?>
However, if that is not an option, you can use Server Side Includes:
File in the same dir:
<!--#include file="header.html"-->
File in a different dir:
<!--#include virtual="/header.html"-->
You'll need a Linux/Apache (not Windows) server for this to work. You'll also need to use the .shtml file extension.
Alternatively, given that you want to keep .html extensions, you can make Apache "think" that all .html files are actually .php:
Create a .htaccess file at the root of your website and add this line:
AddType application/x-httpd-php .html .htm
If your are running PHP as CGI (probably not the case), you should write instead:
AddHandler application/x-httpd-php .html .htm
(Taken from this answer)
If you would like to use PHP to achieve, this, you can do something similar to the code below. You'll have 2 "template" files, and then however many "content" files you need.
header.php will include content on the header (logo, nav menu, etc)
footer.php will include content on the footer (bottom navigation, copyright, disclaimers, etc.)
content.php will include the actual content you wish to display. You can have an infinite number of "content" pages.
Note that while these files have .php extensions, HTML code still works perfectly fine. So you can do something like this for every content.php:
content.php
<?php include "header.php"; ?>
<div class="content">
Your page content will go here
</div>
<?php include "footer.php"; ?>
header.php
<html>
<body>
<div class="header">
Header content such as nav bar here
</div>
footer.php
<div class="footer">
Footer content such as copyright here
</div>
</body>
</html>
In this way, you can change the contents of header.php and footer.php just once, and the changes will be reflected in all the pages you've included the files in.
If you have any further questions or would like something explained again, feel free to post a comment.
In fact, if you are doing only front-end stuff like I do, using load() with jQuery is more than enough. Just like what Skitty and fskirschbaum said.
But I would like to add a few points,
1. based on #Skitty's comment, it is important to load your navbar.html on the server side, like simply host it on your github.io website and refer to it by its URL like
$(document).ready(function() {
$('#nav-container').load('https://berlinali.github.io/test%20header%20template/header.html #nav');}
2. if you have css file, just put it inside < style >< /style> in the < header > part of your html file.
I push my code on github if you need some reference. Hope it helps!
https://github.com/BerlinaLI/berlinali.github.io/tree/master/test%20header%20template
You can use server side scripting languages like php or ruby. Or you can create some say menu.json file and create menu from that in javascript.
With serverside you should setup server or you can use XAMPP for fast setup.
Create header.html with all your menu links
Inlude menu file by using <?php include 'header.html'; ?> line (all files where you use it should be with .php extension or you can edit php config file for .html extension)
PHP would probably be the best method in this case, but since it sounds like you already have everything set up in pure HTML and JavaScript, you could consider using jQuery to load an external file into the DOM.
jquery.load('header.html')
This, of course has its own set of concerns, but you can effectively control everything from a simple .js framework without having to use php includes and doesn't require an iFrame.
You'd still potentially want to address a fallback for browsers without JavaScript turned on, so I only suggest this without knowing all the details, and I would still suggest that php would still be a better solution since you're allowing the server to do the heavy lifting.
I figured it out myself, you can use a JavaScript file and use document.write then put this where you want it to go:
<script type="text/javascript" src="/js/sidebar.js"/>
Here's my js file:
document.write("<div id='sidebartop'>");
document.write("<p>Navigation</p>");
document.write("</div>");
If you want to use both double quotes and single quotes inside the line, be careful with that, and I think that the < and > signs have to be in double quotes. Here's my full code:
----/js/sidebar.js----
document.write("<div id='sidebartop'>");
document.write("<p>Navigation</p>");
document.write("</div>");
document.write("<div id='sidebar'>");
if (page==1) { var p=" style='text-decoration: underline;'" } else { var p=" style='text-decoration: normal;'" }
if (page==2) { var pp=" style='text-decoration: underline;'" } else { var pp=" style='text-decoration: normal;'" }
if (page==3) { var ppp=" style='text-decoration: underline;'" } else { var ppp=" style='text-decoration: normal;'" }
if (page==4) { var pppp=" style='text-decoration: underline;'" } else { var pppp=" style='text-decoration: normal;'" }
if (page==5) { var ppppp=" style='text-decoration: underline;'" } else { var ppppp=" style='text-decoration: normal;'" }
document.write("<p><"+'a href="http://brandonc.handcraft.com/"'+p+">Home</a></p>");
document.write("<p><"+'a href="http://brandonc.handcraft.com/about"'+pp+">About The Author</a></p>");
document.write("<p><"+'a href="http://brandonc.handcraft.com/sevenmages"'+ppp+">The Seven Mages</a></p>");
document.write("<p><"+'a href="http://brandonc.handcraft.com/comment"'+pppp+">Leave A Comment</a></p>");
document.write("<p><"+'a href="http://brandonc.handcraft.com/calender"'+ppppp+">Calender</a></p>");
document.write("</div>");
----In place where you want code to go----
<script>var page=5</script>
<script type="text/javascript" src="/js/sidebar.js"/>
Probably not the most efficient, and I'd defiantly recommend using PHP like in the other answers, but this works for me and doesn't need a .php after every url.
Simply use jQuery .load(). It is very easy to use. Here's an example
navbar.html
<div>This is the navigation bar</div>
index.html
<!DOCTYPE html>
<html>
<head>
<title>Home Page</title>
</head>
<body>
<!--HEADER-->
<div id="nav-container"></div>
<!--HEADER-->
<p>This is the homepage.</p>
<script type="text/javascript">
$(document).ready(function() {
$('#nav-container').load('header.html');
});
</script>
</body>
</html>
about.html
<!DOCTYPE html>
<html>
<head>
<title>About Page</title>
</head>
<body>
<!--HEADER-->
<div id="nav-container"></div>
<!--HEADER-->
<p>This is the about page.</p>
<script type="text/javascript">
$(document).ready(function() {
$('#nav-container').load('header.html');
});
</script>
</body>
</html>

Multiple distinct pages in one HTML file

Is there any way to have multiple distinct HTML pages contained within a single HTML file? For example, suppose I have a website with two pages:
Page 1 : click here for page 2
and
Page 2 : click here for page 1
Can I create a single HTML file that embeds simple static HTML for both pages but only displays one at a time? My actual pages are of course more complicated with images, tables and javascript to expand table rows. I would prefer to avoid too much script code. Thanks!
Well, you could, but you probably just want to have two sets of content in the same page, and switch between them. Example:
<html>
<head>
<script>
function show(shown, hidden) {
document.getElementById(shown).style.display='block';
document.getElementById(hidden).style.display='none';
return false;
}
</script>
</head>
<body>
<div id="Page1">
Content of page 1
Show page 2
</div>
<div id="Page2" style="display:none">
Content of page 2
Show page 1
</div>
</body>
</html>
(Simplified HTML code, should of course have doctype, etc.)
I used the following trick for the same problem. The good thing is it doesn't require any javascript.
CSS:
.body {
margin: 0em;
}
.page {
width: 100vw;
height: 100vh;
position: fixed;
top: 0;
left: -100vw;
overflow-y: auto;
z-index: 0;
background-color: hsl(0,0%,100%);
}
.page:target {
left: 0vw;
z-index: 1;
}
HTML:
<ul>
<li>Click here for page 1</li>
<li>Click here for page 2</li>
</ul>
<div class="page" id="one">
Content of page 1 goes here.
<ul>
<li>Back</li>
<li>Page 2</li>
</ul>
</div>
<div class="page" id="two">
Content of page 2 goes here.
<ul style="margin-bottom: 100vh;">
<li>Back</li>
<li>Page 1</li>
</ul>
</div>
See a JSFiddle.
Added advantage: as your url changes along, you can use it to link to specific pages. This is something the method won't let you do.
Hope this helps!
have all the pages in distinct div areas
<div style="" id="page1">
First Page Contents
</div>
<div style="display:none" id="page2">
Second Page Contents
</div>
then use a js script to workout what you are viewing (like within an hashtag style) to navigate. Either that, or ajax to get the response from a specific file (like /pages/page1.html)
var $prehashval = "";
function loop()
{
if (location.hash.slice(1)!=$prehashval)
hashChanged();
$prehashval = location.hash.slice(1);
setTimeout("loop()", 100);
}
function hashChanged()
{
var $output;
switch (location.hash.slice(1))
{
case "page1":
document.getElementById('page1').style.display = "";
document.getElementById('page2').style.display = "none";
break;
case "page2":
document.getElementById('page1').style.display = "none";
document.getElementById('page2').style.display = "";
break;
default:
$output = location.hash.slice(1);
}
}
loop();
Have you considered iframes or segregating your content and using a simple show/hide?
Edit If you want to use an iframe, you can have the contents of page1 and page2 in one html file. Then you can decide what to show or hide by reading the location.search property of the iframe. So your code can be like this :
For Page 1 : iframe.src = "mypage.html?show=1"
For Page 2 : iframe.src = "mypage.html?show=2"
Now, when your iframe loads, you can use the location.search.split("=")[1], to get the value of the page number and show the contents accordingly. This is just to show that iframes can also be used but the usage is more complex than the normal show/hide using div structures.
JQuery Mobile has multipage feature. But I am not sure about Desktop Web Applications.
This is kind of overriding the thing of one page, but... You could use iframes in HTML.
<html>
<body>
<iframe src="page1.html" border="0"></iframe>
</body>
</html>
And page1.html would be your base page. Your still making multiple pages, but your browser just doesn't move. So lets say thats your index.html. You have tabs, you click page 2, your url wont change, but the page will. All in iframes. The only thing different, is that you can view the frame source as well.
Screen Rec
You could use Colker, which is built for this, but you'll have to remove the search box, and search feature code, because searching isn't compatible with the type of content you intend to use.
Page contents are stored in a java-script array, and the "page" (eg: ?page=pagename) URL parameter determines which page content to serve.
Twine is an open-source tool for telling interactive, nonlinear stories.
It generates a single html with multiples pages.
Maybe it is not the right tool for you but it could be useful for someone else looking for something similar.
By hiding and showing one another, you can achieve this without embedding it. While Guffa's answer worked quite well, I couldn't figure out how to add more than 2 pages, and while Binz Nakama's answer fixes that, it doesn't quite let you only show Page 1 and toggle between them.
Here's the codepen I made, and here's an example I made from one of my existing websites.
HTML:
<div class="part1">
Page 1 content goes here.
<button onclick="hidePart1()">Go to Page 2</button>
<button onclick="showPart3()">Go to Page 3</button>
</div>
<div class="part2">
Page 2 content goes here.
<button onclick="hidePart2()">Go to Page 1</button>
<button onclick="showPart3()">Go to Page 3</button>
</div>
<div class="part3">
Page 3 content goes here.
<button onclick="hidePart2()">Go to Page 1</button>
<button onclick="hidePart1()">Go to Page 2</button>
</div>
CSS:
.hide {
display: none !important;
}
.show {
display: block !important;
}
.part1 {
display: block;
}
.part2 {
display: none;
}
.part3 {
display: none;
}
JS:
function hidePart1() {
document.querySelector(".part1").classList.remove("show");
document.querySelector(".part1").classList.add("hide");
document.querySelector(".part3").classList.remove("show");
document.querySelector(".part3").classList.add("hide");
document.querySelector(".part2").classList.add("show");
}
function hidePart2() {
document.querySelector(".part2").classList.remove("show");
document.querySelector(".part2").classList.add("hide");
document.querySelector(".part3").classList.remove("show");
document.querySelector(".part3").classList.add("hide");
document.querySelector(".part1").classList.add("show");
}
function showPart3() {
document.querySelector(".part1").classList.remove("hide");
document.querySelector(".part1").classList.remove("show");
document.querySelector(".part1").classList.add("hide");
document.querySelector(".part2").classList.remove("hide");
document.querySelector(".part2").classList.remove("show");
document.querySelector(".part2").classList.add("hide");
document.querySelector(".part3").classList.remove("hide");
document.querySelector(".part3").classList.add("show");
}
While the code above is probably not quite optimized (especially the JS), it definitely works well for me. I am still quite new to JavaScript, and not very good at it.
Edit: Added part 3 to the code.
Edit: Added example.
It is, in theory, possible using data: scheme URIs and frames, but that is rather a long way from practical.
You can fake it by hiding some content with JS and then revealing it when something is clicked (in the style of tabtastic).
Solution 1
One solution for this, not requiring any JavaScript, is simply to create a single page in which the multiple pages are simply regular content that is separated by a lot of white space. They can be wrapped into div containers, and an inline style sheet can endow them with the margin:
<style>
.subpage { margin-bottom: 2048px; }
</style>
... main page ...
<div class="subpage">
<!-- first one is empty on purpose: just a place holder for margin;
alternative is to use this for the main part of the page also! -->
</div>
<div class="subpage">
</div>
<div class="subpage">
</div>
You get the picture. Each "page" is just a section followed by a whopping amount of vertical space so that the next one doesn't show.
I'm using this trick to add "disambiguation navigation links" into a large document (more than 430 pages long in its letter-sized PDF form), which I would greatly prefer to keep as a single .html file. I emphasize that this is not a web site, but a document.
When the user clicks on a key word hyperlink in the document for which there are multiple possible topics associated with word, the user is taken a small navigation menu presenting several topic choices. This menu appears at top of what looks like a blank browser window, and so effectively looks like a page.
The only clue that the menu isn't a separate page is the state of the browser's vertical scroll bar, which is largely irrelevant in this navigation use case. If the user notices that, and starts scrolling around, the whole ruse is revealed, at which point the user will smile and appreciate not having been required to unpack a .zip file full of little pages and go hunting for the index.html.
Solution 2
It's actually possible to embed a HTML page within HTML. It can be done using the somewhat obscure data: URL in the href attribute. As a simple test, try sticking this somewhere in a HTML page:
blah
In Firefox, I get a "blah" hyperlink, which navigates to a page showing the FOO heading. (Note that I don't have a fully formed HTML page here, just a HTML snippet; it's just a hello-world example).
The downside of this technique is that the entire target page is in the URL, which is stuffed into the browser's address input box.
If it is large, it could run into some issues, perhaps browser-specific; I don't have much experience with it.
Another disadvantage is that the entire HTML has to be properly escaped so that it can appear as the argument of the href attribute. Obviously, it cannot contain a plain double quote character anywhere.
A third disadvantage is that each such link has to replicates the data: material, since it isn't semantically a link at all, but a copy and paste embedding. It's not an attractive solution if the page-to-be-embeddded is large, and there are to be numerous links to it.
going along with #binz-nakama, here's an update on his jsfiddle with a very small amount of javascript. also incoporates this very good article on css navigation
update on the jsfiddle
Array.from(document.querySelectorAll("a"))
.map(x => x.addEventListener("click",
function(e){
Array.from(document.querySelectorAll("a"))
.map(x => x.classList.remove("active"));
e.target.classList.add("active");
}
));
Let's say you have multiple pages, with id #page1 #page2 and #page3. #page1 is the ID of your start page. The first thing you want to do is to redirect to your start page each time the webpage is loading. You do this with javascript:
document.location.hash = "#page1";
Then the next thing you want to do is place some links in your document to the different pages, like for example:
Click here to get to page 2.
Then, lastly, you'd want to make sure that only the active page, or target-page is visible, and all other pages stay hidden. You do this with the following declarations in the <style> element:
<style>
#page1 {display:none}
#page1:target {display:block}
#page2 {display:none}
#page2:target {display:block}
#page3 {display:none}
#page3:target {display:block}
</style>
An example that actually uses two separate HTML files. The example is based on this tutorial from Tutorial Republic.
app.js
$(document).ready(function(){
$("#screen").load("page1.html")
$(document).on("click", '#page1_button', function(event) {
$("#screen").load("page2.html")
});
$(document).on("click", '#page2_button', function(event) {
$("#screen").load("page1.html")
});
});
Index.html
<!DOCTYPE html>
<html lang="eng">
<head></head>
<body>
<div id="screen"></div>
<!-- Import JQuery -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<!-- Import main JS -->

page2.html
<div>Welcome to page two</div>
<button id="page2_button" type="button">Go to page 1</button>
Important: Page one and page two should only have the body content, i.e., without <body> and <HTML> tags.
In case the container should span over the whole page (taken from this StackOverflow answer):
stycle.css

position:fixed;
padding:0;
margin:0;
top:0;

alternative to using frames in html

Is there any alternative for using a frame. I'm just a beginner and I still don't know what the web designers are doing.
Almost all of the websites I see. Retains the header in the page. How can I apply that so I can stop from using frames.
Use a server-side language like PHP in order to generate a full HTML page.
For example, create three files:
header.php
page.php
footer.php
In the header.php file you have to put the first part of the HTML page.
In the page.php file you have to put the main content of the HTML page.
In the footer.php file, like the header.php, you have to put the end part of the HTML page.
So you can change the page file and the header and the footer remain.
header.php:
<html>
<head>
</head>
<body>
<div id="header">
Place your header here.
</div>
page.php:
<?php include('header.php'); ?>
<div id="main_content">
Place your page content here.
</div>
<?php include('footer.php'); ?>
footer.php:
<div id="footer">
Place your footer here.
</div>
</body>
</html>

In regards to what you see in most websites, they just reuse the same code.. (usually in an external file and insert it in all their pages)..
Take a look at Server Side Includes for more info
Depending on what you wish to display you could look at using divs or using includes.
