Css and html issue with classes - html

I am trying to make a website for school about gothic cathedrals, and can not get the css class to work. I am trying to make a menu on the side of the page that will stay in the same position, and just typed 'hi' to test it. Nothing I have looked up is working and it would be greatly appreciated if someone could tell me what I'm doing wrong.
<html type = "text/css">
<head>
<script>
div.mydiv {
color: red;
position: fixed;
left: 0;
top: 200px; /* 200px from top */
}
</script>
<title>
Cathedral Project
</title>
</head>
<body>
<h1>
<marquee behavior = "alternate" style = "background-color:#828180" scrolldelay = "1">
<img src="gothic.jpg">
</marquee>
</h1>
<div class="mydiv">hi
</div>
</body>
</html>

Currently your css is in a <script> tag. It needs to be in a <style> tag. It should look like this:
<style type="text/css">
.mydiv { /* styles go here */ }
</style>

Change
<script>
div.mydiv {
color: red;
position: fixed;
left: 0;
top: 200px; /* 200px from top */
}
</script>
To
<style>
div.mydiv {
color: red;
position: fixed;
left: 0;
top: 200px; /* 200px from top */
}
</style>

You place your CSS code in the <style type="text/css"></style> tag, not in the <script></script> tag.
And it would be great for you if you indent the code, it will help you not making silly errors like missing the tags.

MapBox Background Image

Good morning everyone,
I have a quick question about some background images in MapBox. For those who don't know MapBox, it is a online provider of custom maps that quickly create beautiful interactive maps and data visualizations. I created a map project, and wanted to put that map as a background image. I am given an embed option and here is my code so far:
<!DOCTYPE html>
<html>
<head></head>
<body>
<iframe width='100%' height='800px' frameBorder='0' src='https://a.tiles.mapbox.com/v4/ericpark.k8ehofdl/attribution,zoompan,zoomwheel,geocoder,share.html?access_token=pk.eyJ1IjoiZXJpY3BhcmsiLCJhIjoiS3pKZ0duVSJ9.tLg7r9w5zppYheaOYcv_DA'></iframe>
</body>
</html>
However, I want the Mapbox html to take the entire background.I have tried placing the url provided into a background-image: url() in css, but it does not function.
body {
background-image: url("https://a.tiles.mapbox.com/v4/ericpark.k8ehofdl/attribution,zoompan,zoomwheel,geocoder,share.html?access_token=pk.eyJ1IjoiZXJpY3BhcmsiLCJhIjoiS3pKZ0duVSJ9.tLg7r9w5zppYheaOYcv_DA");
}
Does anyone know how I might do this?
Thanks,
Eric
Jon here from Stack - I actually do most of the geo stuff here.
If you want to do this the proper way, you're going to have to embed it in a div and put the content that you want over it in its own container div. You can see a pretty straightforward implementation of what you want in the API docs on Mapbox. You can adjust the settings of the map using the JavaScript API (hiding the controls, setting the center, etc.).
L.mapbox.accessToken = 'pk.eyJ1IjoiZXJpY3BhcmsiLCJhIjoiS3pKZ0duVSJ9.tLg7r9w5zppYheaOYcv_DA';
var map = L.mapbox.map('map-container', 'ericpark.k8ehofdl');
html,
body {
height: 100%;
margin: 0px;
padding: 0px
}
#map-background,
#map-container,
#map-overlay,
#content {
width: 100%;
min-height: 100%;
position: absolute;
}
#map-background {
z-index: -1;
}
#map-container {
z-index: 0;
}
#map-overlay {
z-index: 1;
background: none;
}
#content {
z-index: 0;
}
<html>
<head>
<script src='https://api.tiles.mapbox.com/mapbox.js/v2.1.4/mapbox.js'></script>
<link href='https://api.tiles.mapbox.com/mapbox.js/v2.1.4/mapbox.css' rel='stylesheet' />
</head>
<body>
<div id="map-background">
<div id="map-container">
</div>
<div id="map-overlay">
</div>
</div>
<div id="content">
<!-- This is where your regular content should be -->
<p style="color: #fff; text-align: center; font-family: Helvetica; font-size: 2.0em;">This is where your foreground code should be.</p>
</div>
</body>
</html>
Good luck Eric :)
EDIT: Restoring interactivity
I've changed the code to get rid of the overlay and some of the blocking styles. Try that.
L.mapbox.accessToken = 'pk.eyJ1IjoiZXJpY3BhcmsiLCJhIjoiS3pKZ0duVSJ9.tLg7r9w5zppYheaOYcv_DA';
var map = L.mapbox.map('map-container', 'ericpark.k8ehofdl');
html,
body {
height: 100%;
margin: 0px;
padding: 0px
}
#map-container {
width: 100%;
min-height: 100%;
position: absolute;
}
#content {
position: absolute;
}
<html>
<head>
<script src='https://api.tiles.mapbox.com/mapbox.js/v2.1.4/mapbox.js'></script>
<link href='https://api.tiles.mapbox.com/mapbox.js/v2.1.4/mapbox.css' rel='stylesheet' />
</head>
<body>
<div id="map-container">
</div>
<div id="content">
<!-- This is where your regular content should be -->
<p style="color: #fff; text-align: center; font-family: Helvetica; font-size: 2.0em;">This is where your foreground code should be.</p>
</div>
</body>
</html>
To mimic a "background-image" effect with mapbox you could do something like the following:
<!DOCTYPE html>
<html>
<head>
#map_bg {
position:relative;
width:100%;
height:800px;
}
#map_bg iframe {
position:absolute;
top:0px;
left:0px;
height:100%;
width:100%;
}
.content {
z-index:1;
position:relative;
}
</head>
<body>
<div id="map_bg">
<iframe class="mapbox" frameBorder='0' src='https://a.tiles.mapbox.com/v4/ericpark.k8ehofdl/attribution,zoompan,zoomwheel,geocoder,share.html?access_token=pk.eyJ1IjoiZXJpY3BhcmsiLCJhIjoiS3pKZ0duVSJ9.tLg7r9w5zppYheaOYcv_DA'></iframe>
<div class="content">
This is other content on the page.
</div>
</div>
</body>
</html>
You position the map absolutely relative to it's parent which allows content to overlap it (much like a background image). By adding a z-index:1 to the other content you can ensure it appears on top of the map;
I dont think just putting link as background image will work. Mapbox might be rendering map in canvas.
I just found this. Try this. I am not much familiar with mapbox

CSS span hover not working

I am trying to have an image show up when the user hovers over some text in a span. I have gotten it to work for the user hovering over an entire div, but I just want it to trigger over the span. Here's the full code:
<html>
<head>
<title>gif test</title>
<style>
#gif {
position: absolute;
left: 50px;
top: 120px;
display: none;
}
#trigger:hover #gif {
display: block;
}
</style>
</head>
<body style="font-family:Helvetica;">
<h1>gif test</h1>
<hr noshade />
<p>Hover <span id="trigger">here</span></p>
<div id="gif"><img src="img/hey.gif" /></div>
</body>
</html>
I wanted it to be so that when the user puts their mouse over "here", the image shows, but not if the mouse is over "Hover". Is there something special about spans that prevents hovers from working the same way? Or am I referencing the #gif div incorrectly?
Thanks.
Your CSS is incorrect, #trigger;hover #gif means a child of #trigger:hover with the id gif. Meaning your DOM is supposed to be:
<div id='trigger'>
<div id='gif'><img src='img/hey.gif' /></div>
</div>
If you want to control the state of an element outside the hierarchy, where the controlled element is not a child or a sibling, then CSS isn't enough you need some javascript:
<html>
<head>
<title>gif test</title>
<style>
#gif {
position: absolute;
left: 50px;
top: 120px;
display: none;
}
#gif.show {
display: block;
}
</style>
</head>
<body style="font-family:Helvetica;">
<h1>gif test</h1>
<hr noshade />
<p>Hover <span id="trigger" onmouseover="show()" onmouseout="hide()">here</span></p>
<div id="gif"><img src="img/hey.gif" /></div>
</body>
<script type="text/javascript">
showBox() {
var gifbox = document.getElementById("gif");
gifbox.classList.add("show");
}
hideBox() {
var gifbox = document.getElementById("gif");
gifbox.classList.remove("show");
}
</script>
</html>
Per j08691, I had my hierarchies wrong. New code:
<html>
<head>
<title>gif test</title>
<style>
#gif {
position: absolute;
left: 50px;
top: 120px;
display: none;
}
#trigger:hover + #gif {
display: block;
}
</style>
</head>
<body style="font-family:Helvetica;">
<h1>gif test</h1>
<hr noshade />
<p>Hover <span id="trigger">here</span>
<span id="gif"><img src="img/hey.gif" /></span>
</p>
</body>
</html>
Now, the image is a sibling of #trigger (both have parent <p>; the + is the sibling selector).

HTML/CSS banner not working

I am trying to place a solid color banner that stretches across the top of the screen like on this website, facebook, and others. For some reason I am encountering difficulties doing this
I created a div tag in my HTML file for the banner and tried to apply CSS to the div tag but nothing is working.
<!DOCTYPE html>
<html>
<head>
<style>
#banner {
background-color: #333FF;
font-family: Arial;
position: absolute;
left: 0;
right: 0;
padding:15px;
height:800px;
background-size:100%;
}
</style>
<title>Random Password Generator</title>
</head>
<body>
<div id="banner"><h1>fdsfdsfdsfds</h1></div>
</body>
</html>
I also tried linking to an external CSS file but that isn't working either.
How can I make a simple, solid color banner at the top of the page, on every page?
#333FF is an incorrect color. It should be like this: #333FFF. See the W3C Specification for more info on the length of hex codes (hint: they need to be six characters long).
Working example : http://jsfiddle.net/ntim/SKnxP/
position:absolute; also doesn't seem necessary in your case.
You don't actually need to use position absolute unless you want it to be over the top of anything. Instead, you can just use the following:
<style>
#banner {
background-color: #333FFF;
font-family: Arial;
padding:15px;
height:800px;
background-size:100% 100%;
}
</style>
here is something based on a template I use:
<!DOCTYPE html>
<html>
<head>
<title>Title</title>
<link rel="stylesheet" type="text/css" href="CSS-STYLE-SHEET.css">
<style type="text/css">
body
{
background-color: #E7E7E7;
text-align: center;
font-family: Arial, Helvetica;
font-size: 15px;
color: #000000;
border-spacing: 0;
border-collapse:collapse;
padding: 0;
margin: 0;
}
#Banner {
background-color: #333FFF;
top: 0; /* Probably not necessary... */
height: 40px;
width: 100%; /* Also probably not necessary */
}
#ContentMain
{
background-color: #FFFFFF;
height: 100%;
}
</style>
</head>
<body>
<div id="ContentMain">
<div id="Banner">Banner goes here</div>
Content goes here
</div>
</body>
</html>
should work.. the grey bit at the back is because the html and body tags dont fill the entire screen - something like this should fix it (I would use min-height), but I have not included it here as then if you want a page taller than the browser window and works in Internet Explorer things get annoying...

Pasted text at the top of page

I want to add pasted text (that text goes down when user goes down of the page, etc.) at the top of my page, when somebody haven't got enabled JavaScript, something like that :
How to do this ? Is there any way to that using JavaScript or HTML ? I want not to use jQuery, because I don't know that language so good.
#EDIT : Sorry, that was my error - that cannot use JavaScript if user doesn't have JS enabled :)
This is a sample how you can make a info bar like SO:
HTML:
<noscript><div id="noscript"><p>NO JAVASCRIPT</p></div></noscript>
CSS:
div#noscript {
margin: 0 auto;
width: 100%;
padding: 10px 0;
position: fixed;
top: 0;
background: red;
z-index: 99999;
}
div#noscript p {
text-align: center;
color: white;
}
Here the JSfiddle
http://jsbin.com/AJUxayA/6/edit
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body>
<div id="no_js_header">test</div>
<div id="content">content</div>
<div style="margin-top: 2200px"></div>
</body>
</html>
#no_js_header {
position:fixed;
width:100%;
background-color:red;
margin: 0px;
top: 0px;
left: 0px;
padding: 3px;
}
#content {
position: absolute;
top: 50px;
}
(uncomment for activation in the jsbin)
document.getElementById('no_js_header').style.display = 'none';
You can try using the noscript tag...
<noscript>
<div>
<p>ahhh, javascript is disabled!</p>
</div>
</noscript>

Simple webpage coming up White in Internet Explorer

I have this simple web page, that I thought I had tested in every browser. Then I tried it in Internet Explorer, and it just showed a blank white page. I went through my CSS, looking for lines that IE didn't support, and found background = rgba(some stuff), but this is in a div not shown by IE. Does anybody have any ideas on what might be causing this? The webpage is at http://heather.sh/qr
Below is my HTML.
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<script>
function ifUIWebView() {
var is_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit(?!.*Safari)/i.test(navigator.userAgent);
var isChrome = navigator.userAgent.match('CriOS');
if (isChrome) {
var mobile_safari_div = document.getElementById('mobile_safari_div');
mobile_safari_div.innerHTML = mobile_safari_div.innerHTML + '<font size="3" color="black"><b>Chrome does not support contact card download. Please open this page (http://heather.sh/qr) in Mobile Safari.</b></font>';
}
else if (is_uiwebview) {
var mobile_safari_div = document.getElementById('mobile_safari_div');
mobile_safari_div.innerHTML = mobile_safari_div.innerHTML + '<font size="3" color="black"><b>This browser may not support contact card download. If it doesn\'t work, open this page (http://heather.sh/qr) in Mobile Safari.</b></font>';
}
}
</script>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
</head>
<body>
<div id='topContainer'><img src="photo.jpg" style="visibility:hidden" width="100%"/>
<div id='container'>
<div id='download_button_div'>
<img src="Download Contact.png" id='download_button'></img>
<div id='mobile_safari_div'></div>
</div>
<script>
ifUIWebView()
</script>
</div>
</div>
</body>
And here is my CSS:
html, body {
margin: 0px;
padding: 0px;
overflow: hidden;
}
#topContainer{
position: relative;
max-width:400px;
margin: auto;
}
#container{
width: 100%;
max-width: 400px;
height: 100%;
margin: auto;
background-size: 100%;
background-repeat: no-repeat;
background-image: url("photo.jpg");
position:absolute;
top:0px;
}
#download_button {
width: 100%;
}
#download_button_div {
width: 100%;
}
#mobile_safari_div {
background: rgba(255, 255, 255, 0.5);
font-family: 'helvetica';
text-align: center;
}
Any ideas on what part is incompatible with IE? As I say, I have tried going through and could only find the rgba thing, so any help appreciated.
Thanks!
You should try to use
style = "display: block " instead of style="visibility:hidden"
I am not sure this will help or not.
But try it
I found out what the problem was - I had forgotten to put <!DOCTYPE html> at the top of the html. Not sure what it does, but it fixed everything.
Thanks!
