How to make <hr> full width? - html

I want to make this <hr> so it will stretch the full width, right to the edges of its parent container. I have tried adding margin-left/padding-right to overcome this but it keeps changing when resizing (responsive).
.single-article .article-container-inner {
background: #f0eded;
border: 1px solid #c9c7c7;
padding: 20px;
margin-bottom: 20px;
}
.single-article hr {
margin-top: 30px;
margin-bottom: 20px;
border: 0;
border-top: 1px solid #c9c7c7;
width:100%
}
<div class="article-container single-article">
<div class="article-container-inner">
<hr>
</div>
</div>
(also at http://jsfiddle.net/bh2f6/1/)
Is there a better solution for this?
Edit: I can't edit the parent container's padding as that is needed for bunch of other elements.

Your width:100%; on the <hr /> and the padding on the parent were messing things up. The <hr /> naturally stretches across the screen and doesn't need width:100%, so remove it. Then to compensate for the padding, just add the same negative margin to the <hr />.
Change your CSS to this:
.single-article hr {
margin: 30px -20px 20px;
border: 0;
border-top: 1px solid #c9c7c7;
}
See working jsFiddle demo

Something like this might work...
hr {
padding: 50px 0;
border: none;
&:before {
// full-width divider
content: "";
display: block;
position: absolute;
right: 0;
max-width: 100%;
width: 100%;
border: 1px solid grey;
}
}

HR Secret things, you must know.
When your horizontal rule (hr) leaves 15px from left and right, probably when you use with bootstrap.
<hr class="my-hr-line">
.my-hr-line {
position: relative;
left: -15px;
width: calc(100% + 30px);
height: 2px;
border: 2px solid blue;
}
Hope it will help many one.

Removing Padding should work for you
Working Example
.single-article .article-container-inner {
background: #f0eded;
border: 1px solid #c9c7c7;
margin-bottom: 20px;
}
.single-article hr {
margin-top: 30px;
margin-bottom: 20px;
border: 0;
border-top: 1px solid #c9c7c7;
width:100%
}

You mean like this?

just change the padding to padding: 20px 0;

It's because <hr/> has border (at least in FireFox since <hr/> has browser dependent style).
Remove border first.
hr {
border: none;
border-bottom: 4px solid #469551;
width: 30%;
margin-left: auto;
margin-right: auto;
margin-bottom: 0px !important;

Replace this:

by this:
border: 4px solid #469551;

HTML extend height of div

div.div1 {
position: relative;
border: 1px solid black;
height: 100px;
width: 100px;
padding: 10px;
}
div.div2 {
background-color: gray;
border: 1px solid black;
padding: 10px;
}
div.div3 {
position: absolute;
border: 1px solid red;
height: 20px;
width: 20px;
bottom: 10px;
left: 10px;
}
<div class="div1">
<div class="div2">Test 123</div>
<div class="div3">A</div>
</div>
I use the above code to display a big div with two divs in it. For the first one I use position: absolute to place it on bottom left of the div.
How can I extend the height of the second gray one so that it's 5 pixels above the first, but without having to measure its exact height in pixel (like the pic below)? I can set height: 50px; for example but is there another way?
I would use a flexbox approach rather than absolute positioning (comments in css below)
div.div1 {
display: flex;
flex-direction:column;
/* add the above styles*/
border: 1px solid black;
min-height: 100px; /*I would also change this to min-height otherwise it may cause issues if your text goes to 2 lines*/
width: 100px;
padding: 10px;
}
div.div2 {
flex-grow:1; /* make div grow to fill the space */
margin-bottom:5px; /* minus the amount of margin you wanted */
background-color: gray;
border: 1px solid black;
padding: 10px;
}
div.div3 {
/* remove absolute positioning */
border: 1px solid red;
height: 20px;
width: 20px;
}
<div class="div1">
<div class="div2">Test 123</div>
<div class="div3">A</div>
</div>
EDIT: I suggest that, if you can focus on the modern browser features, going the flexbox way as shown by Pete is definitely a cleaner approach than the ones I've shown bellow. That being said, here are the alternatives:
You can use calc to dynamically determine the height of div2:
div.div1 {
position: relative;
border: 1px solid black;
height: 100px;
width: 100px;
padding: 10px;
}
div.div2 {
background-color: gray;
border: 1px solid black;
padding: 10px;
height: calc(
100%
- 20px /* div1: padding top and bottom */
- 2px /* div1: border top and bottom */
- 20px /* div3: height */
- 2px /* div3: border top and bottom*/
- 5px /* desired separation*/
);
}
div.div3 {
position: absolute;
border: 1px solid red;
height: 20px;
width: 20px;
bottom: 10px;
left: 10px;
}
<div class="div1">
<div class="div2">Test 123</div>
<div class="div3">A</div>
</div>
You can avoid including padding and border width in your calculations if you set the box-sizing for your divs to border-box (You might want to set this for all elements):
div {
box-sizing: border-box;
}
div.div1 {
position: relative;
border: 1px solid black;
height: 100px;
width: 100px;
padding: 10px;
}
div.div2 {
background-color: gray;
border: 1px solid black;
padding: 10px;
height: calc(
100%
- 20px /* div3: height */
- 5px /* desired separation */
);
}
div.div3 {
position: absolute;
border: 1px solid red;
height: 20px;
width: 20px;
bottom: 10px;
left: 10px;
}
<div class="div1">
<div class="div2">Test 123</div>
<div class="div3">A</div>
</div>
There's this rather new, hip CSS property called 'flex' which you're now going to love because it does it exactly that without the need of positioning absolute etc. I did something similar yesterday where I had a vertical nav bar and I wanted one menu at the top and one at the bottom. In a responsive environment; using your approach of positioning absolute it would've resulted in a nasty mess of working out heights to stop the content from overlapping. Flex prevented this! Yeyyyyy
https://css-tricks.com/snippets/css/a-guide-to-flexbox/
In your example you want to do something like this:
.div1 {
display: flex;
flex-direction: column;
flex-wrap: nowrap;
justify-content: space-around;
}
.div2 {
align-self: flex-start;
flex-grow:1;
width:100%;
}
.div3 {
align-self: flex-end;
width:100%;
}
Now your div 3 will always be at the bottom. Although now .div3 will extend the entire width so within the div insert your content and BOOM done.
You can use calc on the heightsetting as in my snippet below. That setting is 100% minus (20 + 10 + 2) for the height, border and bottom of the lower DIV minus (5 + 2) for the distance and the border of the first DIV minus 10px for the padding of the parent, summing up to 49px .
div.div1 {
position: relative;
border: 1px solid black;
height: 100px;
width: 100px;
padding: 10px;
}
div.div2 {
background-color: gray;
border: 1px solid black;
padding: 10px;
height: calc(100% - 49px);
}
div.div3 {
position: absolute;
border: 1px solid red;
height: 20px;
width: 20px;
bottom: 10px;
left: 10px;
}
<div class="div1">
<div class="div2">Test 123</div>
<div class="div3">A</div>
</div>

Div Trying To Be Centered But Not Working

my problem is that I am trying to center a div inside my full-width header like this:
</body>
<!-- the CSS -->
#header {
margin-top: -1em;
margin-left: -1em;
height: 2.95em;
padding:15px 0;
min-width:150%;
background-color: #F4F6F7;
border: 1px solid #E1E1E1;
}
#insideHeader {
border: 1px solid black;
width: 20em;
height: 2.6em;
margin: 0 auto;
}
The result of this code is in the here.
Thanks in advance.
min-width:100%; seem to centre your div...
body {
background-color: red;
margin: 0;
}
#header {
margin: 0;
height: 2.95em;
padding:15px 0;
min-width:100%;
background-color: #F4F6F7;
border: 1px solid #E1E1E1;
}
#insideHeader {
border: 1px solid black;
width: 20em;
height: 2.6em;
margin: 0 auto;
}
<body>
<div id="header">
<div id="insideHeader"></div>
</div>
</body>
or

As my understanding you are trying to fit the outer box in the window and center align the inner box.
Add/Update following styles
html, body {
margin: 0;
padding: 0;
}
#header {
margin-top: -1em;
height: 2.95em;
padding:15px 0;
width:100%;
background-color: #F4F6F7;
border: 1px solid #E1E1E1;
}
There are default padding/margin of browser. You need to override those in order to fit your outer box.
Once you do that, you need to remove your negative left margins which were put in order to make box stick to the boundary of window.
Then set the width to 100%.
For reference - http://jsbin.com/lomeganori/1/edit?html,css,output
give
#header
{
box-sizing: border-box;
//and remove height:2.5rem;
}
box-sizing:borderbox will removes all your troubles, and dont give height to parent
that will automatically take the height of the inner div

Setting up textarea to consume all the available space in a div (minus N pixels at the top)

I am trying to set up a custom toolbar for a textarea, I have the following
html:
<div id="main">
<div id="toolbar"></div>
<textarea></textarea>
</div>
css:
#main {
background-color: #ddd;
height: 400px;
width: 400px;
position: relative;
}
#toolbar {
background-color: #444;
height: 40px;
color: white;
}
textarea {
outline: none;
border: none;
border-left: 1px solid #777;
border-right: 1px solid #777;
border-bottom: 1px solid #777;
margin: 0;
position: absolute;
top: 40px;
bottom: 0;
left: 0;
right: 0;
}
It works exactly as I expected in Chrome, but in firefox / ie the text area is not consuming all the available space in the div.
How do I set it up so the toolbar takes up 40px at the top of the div, and the textarea consumes all the rest of the height.
I am sizing this stuff dynamically so can not use a "px" height or width for the textarea.
Codepen here: http://codepen.io/anon/pen/pDgvq
Better Suggestion
Set the textarea's width and height to 100%. Then, give it a 40px top-border that is transparent (color doesn't really matter, actually). Be sure to set box-sizing to border-box. Now position the relative toolbar on a higher z-index - voila.
Pen: http://codepen.io/anon/pen/nFfam
Oldie
Rather than moving the textarea down, move the toolbar up:
#main {
background-color: #ddd;
height: 200px; width: 400px;
position: relative;
top: 40px;
}
#toolbar {
background-color: #444;
height: 40px; width: 100%;
position: absolute;
top: -40px;
}
textarea {
width: 100%; height: 100%;
box-sizing: border-box;
}
Pen: http://codepen.io/anon/pen/mEGyp
Both Firefox and IE9+ support the calc() CSS function (you're out of luck with IE8 though; not sure what you're supporting).
I've added these lines to the textarea's CSS in your pen (updated version):
width: calc(100% - 2px);
height: calc(100% - 41px);
padding: 0;
The padding is just for normalization; you can choose whatever suits your needs, but be sure to adjust the pixel values in calc() accordingly. The 2px for width are to compensate the left and right border; the 41px for height are 40 for the toolbar and 1 for the bottom border.
Add width:-moz-available; height:100%;resize: none; to textarea
textarea {
outline: none;
border: none;
border-left: 1px solid #777;
border-right: 1px solid #777;
border-bottom: 1px solid #777;
margin: 0;
position: absolute;
top: 40px;
bottom: 0;
left: 0;
right: 0; width:-moz-available; height:100%;
resize: none;
}
UPDATED DEMO
Another Method
You can add a div around textarea and give position:absolute to the div
HTML
<div id="main">
<div id="toolbar"></div>
<div id="container">
<textarea></textarea>
</div>
</div>
CSS
#container{
position:absolute;
bottom:0px;
top:40px;
width:100%
}
textarea {
outline: none;
border: none;
border-left: 1px solid #777;
border-right: 1px solid #777;
border-bottom: 1px solid #777;
resize: none; height:100%; width:99.5%
}
DEMO 2
You can use height and width for textarea in % also apply top to the toolbar div in %
e.g. If top is 10% give 90% height to textarea.
I hope this is your desired result: Demo
#main {
background-color: #ddd;
width: 400px; height: 200px;
padding: 0;
}
div #toolbar {
background: #444;
width: 100%; height: 40px;
}
textarea {
margin: 0;
width: 100%; height: 100%;
}

Left-bottom border

Imagine (or if you can't imagine, watch) this piece of code:
<div class="block"></div>
<style>
.block {
width: 10px;
height: 10px;
display: block;
background-color: red;
border: 1px solid #000000;
border-bottom: 0;
}
</style>
Now look at the bottom line. This is my problem; I want the left and right border to be 1px longer (so the bottom border is the part between the left border and right border).
Is it possible to accomplish this??
This is a way to do it, since the box model does not support what you need, using only one div:
<div class="block"><div></div></div>
and the css:
.block {
width: 10px;
height: 10px;
border: 1px solid #000000;
border-bottom: 0;
padding-bottom: 1px;
}
.block div {
width: 10px;
height: 10px;
background-color: red;
}
This will extend the black border on the left and right side with 1px.
Try this :)
http://jsfiddle.net/z6ASC/
This is possible if you have two containers, one for the outside left/right borders, and one for the inside bottom-border. I've put together a demo showing this.
DEMO:
http://wecodesign.com/demos/stackoverflow-7074782.htm
<style type="text/css">
#borderOutside {
height: 200px;
width: 300px;
border:1px solid #900;
border-bottom: none;
padding-bottom: 5px; /*this is the gap at the bottom*/
}
#borderInside {
height: 100%;
border-bottom: 1px solid #900;
}
</style>
<div id="borderOutside">
<div id="borderInside"><!--Your Content--></div>
</div>
It can be done without adding any extraneous elements in your HTML via this strategy:
.block {
position: relative;
width: 10px;
height: 10px;
display: block;
background-color: red;
}
.block:before {
position: absolute;
content: '';
width: 10px;
height: 11px;
top: -1px;
left: -1px;
border: 1px solid #000;
border-bottom: none;
}
The pseudo element :before is only supported from IE8, but works in all other major browsers.
