How to create a partial-horizontal line in HTML? - html

I would like to create a thin line below the main heading in a webpage, which is centered, something like this. How do I go about it as using /hr will create an end-to-end line.

In your example this is done with css and not with a hr-tag
So either you can use the css-style border-bottom as in your example, or you indeed can use a hr-tag which you give some CSS, e.g.:
<hr style="width:40%">
If you want to position the hr, you may need the position-style.
You can try this easily on the w3c example site.
Remember, that the hr-width-attribute (not the style!) is not working under html5 anymore.

You can use HR tag or HR tag with simple css code
Html HR tag :
<center>Your Code Here</center>
<hr align="center" width="50%">
Here HR tag with simple css code:
hr {
width: 50%;
margin-left: auto;
margin-right: auto;
}
<center>Your sample code here</center>
<hr>
Note:
The attributes that aren't supported in the HTML5 spec are all related to the tag's appearance. The appearance should be set in CSS, not in the HTML itself.
So use the <hr> tag without attributes, then style it in CSS to appear the way you want.

You can adjust HR width
<hr width="50%">
Or in the example you gave it is using css property of the div with a bottom border
#yourDiv {
border-bottom: 1px solid gray;
}

you can restyle and add margin to your hr
hr {
border:none;
border-top:1px solid;/* or bottom */
margin:1em 15%; /* 15% or whatever fixed or % value that suits your needs*/
}
body {text-align:center;}
<h1>Any content before</h1>
<hr/>
<p>any content after</p>
width a fixed width margin is involved too
hr {
border:none;
border-top:1px solid;/* or bottom */
margin:1em auto;
width:17em;
}
body {text-align:center;}
<h1>Any content before</h1>
<hr/>
<p>any content after</p>
You can also use the border-bottom of any tag ...
h1 {
border-bottom:1px solid;
padding-bottom:0.5em;
display:table; /* to fit to content's width else margin or a fixed width works too */
margin:1em auto; /* if not display:table use width or margin values as first snippet */
}
body {text-align:center;}
<h1>Any content before</h1>
<p>any content after</p>

HTML:
CSS:
. hr {
width: 50%
color: #222
}

html:
<h1> Your code </h1>
<hr>
CSS:
hr {
align-content : center;
width : 20%;
margin-left : auto;
margin-right : auto;
}
The hr style settings are to be done in CSS not in the body.
Edit: I used width to control the length of the horizontal line that will appear below my heading or text. Margin-left and margin-right :auto, automatically placed the line in the center where as normally the line would begin at one end of the page and end in another.

DIV as filling block in another DIV

I have a CSS
.nav {
width: 200px;
line-height: 50px;
float: left;
}
.content {
margin: 0px 0px 0px 230px;
}
.container {
border: 1px solid red;
}
And here is the HTML
<body>
<div class="container">
<div class="nav">Some text
<br>more text
<br>even more text
</div>
<div class="content">
<h1>Home</h1>
<p>Text paragraph</p>
</div>
</div>
</body>
This gives me menu on the left and the content on the right. And a red box around the content on the right, but only the half menu on the left.
But I would like to have the red box also around the complete nav-div Can anyone help?
Thanks

Add overflow:auto to your container div's CSS:
.container {
border: 1px solid red;
overflow:auto;
}
jsFiddle example
Floating the child div removes it from the flow of the document and the container essentially collapses as if it didn't exist. Adding the overflow restores the behavior you're after.
I think this is a quick fix if you float your container it should solve the problem your having. See here http://jsfiddle.net/1540sscj/
.container {
border: 1px solid red;
float:left;
width:100%;
}
Floating an element removes it from the normal flow of the page with one side effect being that its parent's dimensions won't expand to fit it.
So, what you need to do is clear the floated item. The best way to do this, without using additional markup or using the overflow property, which may cause other issues, depending on your layout, is to use the :after pseudo class on the parent element, like so:
.nav{
width:200px;
line-height:50px;
float:left;
}
.content{
margin:0px 0px 0px 230px;
}
.container{
border:1px solid red;
}
.container::after{
clear:both;
content:"";
display:block;
height:0;
width:0;
}
<body>
<div class="container">
<div class="nav">Xalsdk fjaskldfj alskdfj asädf<br>asdf<br>asdf</div>
<div class="content">
<h1>Home</h1>
<p>Bla bla.</p>
</div>
</div>
</body>
More information on clear
More information on pseudo elements
Best way imho would be to add a div like:
<div style="clear:both;"></div>
Under your floating elements: FIDDLE
This way you don't need to use oveflow:hidden on your container that may give you problems once you have more stuff in your project.
Also you shoudn't use a margin-left for your content as the previous element is already floating left. The best practise if you want to add some margin between nav and content would be to make your content float left as well and then use margin left (the exact size you want) with respect of the nav and not with the left of the window.
Finally, if you don't want to add the clear:both div to the html you could add somethign like
.content:after {
content:'';
display:block;
clear: both;
}
it's a bit less browser (old ones) compatible but cleaner
You have to add overflow:auto to .container in your css
Check my js fiddle
Also the css that modified.
.container {
border: 1px solid red;
overflow:auto;
}
Description of property overflow from MDN
The overflow property specifies whether to clip content, render
scrollbars or just display content when it overflows its block level
container.

background-color not extending to the entire element

This is my CSS code:
#outer {
width:580px;
padding:10px;
float:left;
}
.inner {
width:560px;
padding: 10px;
background-color:#fff;
color:#666666;
}
And the HTML:
<div id="outer">
<div class="inner">
... a lot of content
</div>
</div>
My problem is the background-color for the inner div doesn't extend to fill the entire div alongside its content. I've had this problem quite often, and my solution has usually been to specify a height for #inner, which makes the background fill #inner accordingly. However, I don't want to specify a height explicitly because it's dynamic content. What should I do to make the background-color fill the div as it extends?
Set the position of each element, with the inner element needing to be absolute, and then just tell the inner div to always fill the outer one with height: 100%. The only care that you have to take with this is that setting the position of inner to absolute will then make it ignore floats, but presumably you are taking care of that with outer.
(I changed the background color to red in this answer to make it more obvious what is going on.)
This is my CSS code:
#outer {
position: relative;
width:960px;
height: 500px;
}
.inner {
position:absolute;
height:100%;
width:400px;
background-color: red;
}
And the HTML:
<div id="outer">
<div class="inner">
... a lot of content
</div>
</div>
I couldn't replicate your issue. If you don't specify a height for '.inner', the background color should extend dynamically as '.inner' fills with content.
You might be having an issue due to a lack of a CSS reset. Each browser has a set of standard css rules it applies to all pages, unless you override these rules.
I recommend adding a CSS reset in your above all your current css.
A very basic but popular reset is by Eric Meyer, found here: http://meyerweb.com/eric/tools/css/reset/
Let me know if that helps, and if not try posting an image of what you are experiencing.
Btw, this is how your code renders for me:
The padding of the outer element will always show the background color of the outer element...
Just remove the padding there.
#outer {
width:580px;
/* padding: 10px;*/
background:red;
border:1px solid green;
}
.inner {
width:560px;
padding: 10px;
background-color:lightblue;
color:#666666;
}

Beginner issue with <div>

I'm making a website with the title in a div box at the top of the page. The issue is that when i put a heading in the box it doesn't stay in the box
<div style="width:1000px;height:40px;background:grey;border:3px solid;border-radius:10px;opacity:0.85;overflow:hidden;">
<h1 style="text-align:center;">
Welcome To A Website
</h1>
</div>
When you create a HTML file, each browser interpret the elements on its way. For example: some browsers have an extra margin config at an <p> or some different line-height property. Because of that, normally, the developers use a Reset CSS (example: http://meyerweb.com/eric/tools/css/reset/). It reduce browser inconsistencies in things like default line heights, margins and font sizes of headings, and so on.
In your case, h1 by default have some configs that make it go out of the div box (margin and padding, as I checked). You can solve it using: margin: 0; padding: 0; at <h1> element. My suggestion for future projects: use a Reset CSS and you'll have more control in things like that.
Another suggestion: use a CSS file to organize your own styles. Inline styling isn't a good thing when you've a common thing to modify and have to go file by file to do that. With CSS you only change the file and it reflects at all HTML that uses it.
Well, my CSS fix suggestion is:
HTML:
<div>
<h1>Welcome to a Website </h1>
</div>
CSS:
div {
/* Make title go to entire screen*/
width: 100%;
display: block;
/* You visual config */
height:40px;
background:grey;
border:3px solid;
border-radius:10px;
opacity:0.85;
overflow:hidden;
line-height:40px;
}
div h1 {
margin: 0;
padding: 0;
text-align:center;
}
I used width:100%;display:block instead of width:1000px because I assumed that you want a block that occupies 100% width from screen. Working demo: http://jsfiddle.net/brunoluiz/NyLAD/
Well, good luck with HTML and CSS studies!
You can set the margin of your h1 to 0, also note that you should place the styles in some CSS file or right inside the page (between the <style> tags):
div {
width:1000px;
height:40px;
background:grey;
border:3px solid;
border-radius:10px;
opacity:0.85;
overflow:hidden;
line-height:40px;
}
div h1 {
margin:0;
}
Working demo.
Because you specified a specific height for the box in the style. Try removing the "height:40px;" part.
Now the div style looks like this:
style="width:1000px;background:grey;border:3px solid;border-radius:10px;opacity:0.85;overflow:hidden;"
Fiddle
It looks like the height of the size of the header is too big for the height you set on your div. Try taking out the height from the div's style, like so:
<div style="width:1000px;background:grey;border:3px solid;border-radius:10px;opacity:0.85;overflow:hidden;">
<h1 style="text-align:center;">
Welcome To A Website
</h1>
</div>

Simple CSS centering (centering text + tall image inside a div)

I have been trying to do the following. I have a <div> element
which spans the whole width of its parent div. Inside of this
I would like to place A. some text and B. an image.
A. some text (either loose text or text enclosed in a <p>, <h2>,
or <span>, or <div> element), on the left.
B. an image defined via an <img> element whose both height and width
are known.
Other requirements:
There must be 12px of space between the text and the <img> element.
Important: both the text from A. and the image from B. must be
centered as a group.
The text from A. must be vertically centered in its enclosing space.
How can I achieve this effect? I have tried different things but cannot
manage to place the image to the right of the text and cannot manage to
have the text A. vertically centered.
Anyone know how to solve this simple problem?
Thank you all for your answers, seems CSS makes simple things so hard,
anyways:
div#content_whatsnew, div#content_bestsellers { clear: both; height: 108px; font-size: xx-large; text-transform: uppercase; margin-left: 380px; }
div#content_whatsnew p, div#content_bestsellers p { float: left; height: 108px; line-height: 108px; padding: 8px 12px 0px 0px; color: black; }
div#content_whatsnew img, div#content_bestsellers img { float: left; height: 108px; }
Is this what you are trying to achieve? http://dabblet.com/gist/3130292
Is this about right?
http://jsfiddle.net/89twb/2/
For aligning text, check this out.
And for placing elements next to each other, this.
This should work:
<div class="my-outer-container">
<div class="my-inner-container">
<div class="my-text">Here is my text, it is lovely text.</div>
<img src="my-image.jpg" alt="" class="my-image" />
</div>
</div>
.my-outer-container {
width:auto;
text-align:center;
}
.my-inner-container {
width:XXXpx; /* enter whatever the width you want here is */
margin:0 auto;
overflow:auto;
}
.my-text {
width:XXXpx; /* enter whatever the width you want here is */
float:left;
margin-right:12px;
}
.my-image {
width:XXXpx; /* enter whatever the width you want here is */
height:XXXpx; /* enter whatever the height you want here is */
float:left;
}
Then maybe use the vertical centering tip on the link provided above by #biziclop
The most intuitive way would be using 'vertical-align:middle;' but it often tends not the way you want it to work.
I did some research and found this code from here. http://phrogz.net/css/vertical-align/index.html
Hope this helps!
<style type="text/css">
#myoutercontainer { position:relative }
#myinnercontainer { position:absolute; top:50%; height:10em; margin-top:-5em }
</style>
<div id="myoutercontainer">
<div id="myinnercontainer">
<p>Hey look! I'm vertically centered!</p>
<p>How sweet is this?!</p>
</div>
</div>
In order to center a div, it has to have a fixed width. If it spans the width of its parent div, you can only then center things inside it. So it sounds to me like the best solution would be to place your text in a fixed-width left-floated div, and do the same for your image, and then place those both in a fixed-width holder div, which is centered with margin:auto;
Here's an example: http://dabblet.com/gist/3130148
Edit- I vertically centered the text by placing it in a table. Tables are the only surefire way to vertically center something cross-browser.

How to achieve table's centering capabilities without tables

For me, one of the most useful features of tables is that their width adjust to its content.
You can very easily do things like:
<table align=center style="border: 1px solid black">
<tr><td style="padding: 20px">
some text here
</table>
If the content of that box is wider, the box will be wider. Very intuitive and it works on ALL browsers, period.
You can achive something similar for normal block elements by using the float CSS property, i.e. their width adjust to its content. But the element will not be centered.
So, the question: How can you center a block element and make that element to adjust its width to its content in a cross-browser manner?
The modern way is to specify display:table and the workaround for IE is having a parent element and text-align:center on a inline/inline-block:
<div id="for-ie">
<div id="el">whatup son</div>
</div>
<style>
#el {
display:table;
margin:0 auto;
}
/* for IE, throw this in a CC */
#for-ie { text-align:center; }
#el {
zoom:1;
display:inline;
}
</style>
Demo
Here's a quick tutorial I wrote on this subject: http://work.arounds.org/centering-block-level-element-variable-width/
I'll lengthen it when I'm not sleepy.
Quoting CSS: The Definitive Guide by Eric Meyer
If both margins are set to auto, as shown in the code below, then they are set to equal lengths, thus centering the element within its parent:
p {width: 100px; margin-left: auto; margin-right: auto;}
Setting both margins to equal lengths is the correct way to center elements, as opposed to using text-align. (text-align applies only to the inline content of a block-level element, so setting an element to have a text-align of center shouldn't center it.)
In practice, only browsers released after February 1999 correctly handle auto margin centering, and not all of them get it completely right. Those that do not handle auto margins correctly behave in inconsistent ways, but the safest bet is to assume that outdated browsers will reset both margins to zero.
However,
One of the more pernicious bugs in IE/Win up through IE6 is that it actually does treat text-align: center as if it were the element, and centers elements as well as text. This does not happen in standards mode in IE6 and later, but it persists in IE5.x and earlier.
If your intend is to display just some text at the middle of the page, you can use something like this:
<div style="text-align:center;">
<div style="background:red;display:inline;">
Hello World!
</div>
</div>
The first block will align contents to the middle. The second will fill the height equal to its contents, since display:inline will force the <div/> block to behavior like a <span/>, ie. adjust its width to content, and not to the remaining space.
Note this is limited to single line text only (like "some text here").
Use this CSS
#content {
position: absolute;
width: 150px;
margin-left: -75px;
left: 50%;
border: 1px solid #000;
text-align: center;
padding: 20px;
}
and this html
<div id="content">
some text here
</div>
Good golly, miss Molly! These answers are really overcomplicated.
CSS:
div.centered {
width:100%;
margin:0 auto;
text-align:center;
}
div.centered span {
padding:20px;
border:1px solid #000;
}
And then use this in your body:
<div class="centered"><span>Hello world!</span></div>
