This is my CSS code;
#wrap {
width:50em;
max-width: 94%;
margin: 0 auto;
background-color:#fff;
}
#head {
width:50em;
height:10em;
max-width: 100%;
margin: 0 auto;
text-align:center;
position: relative;
}
#css-table {
display: table;
margin: 1em auto;
position: relative;
width:50em;
max-width: 100%;
}
#css-table .col {
display: table-cell;
width: 20em;
padding: 0px;
margin: 0 auto;
}
#css-table .col:nth-child(even) {
background: #fff;
}
#css-table .col:nth-child(odd) {
background: #fff;
border-right: 4px double #b5b5b5;
}
And my HTML code;
<div id="cont">
<div id="css-table">
<div class="col">123</div>
<div class="col">123</div>
</div>
</div>
When I scale the Firefox window, the table scales fine even down to 300px width viewport...just like I want to. But in Chrome, the table looks normal only when the viewport is wider than 50em. If I narrow the Chrome window, the table bleeds out on the right side of the wrap.
Is there a reason why is Chrome doing this?
Technically Chrome is following the rules because max-width should only apply to block elements.
From MSDN docs:
The min-width/max-width attributes apply to floating and absolutely
positioned block and inline-block elements, as well as some intrinsic
controls. They do not apply to non-replaced inline elements, such as
table rows and row/column groups. (A "replaced" element has intrinsic
dimensions, such as an img or textArea.)
The table (or in your case display:table) should technically not work or be supported. FF apparently obeys it fine, but you'll probably need to come up with another solution, either removing the display:table or the max-width.
max-width property
MSDN Doc
The solution I found was using table-layout: fixed and width: 100%
Create a div and give it a styling to display block and a max width. You may use traditional <table> and give it a styling of 100% width.
I was able to use a mixin(SASS) to fix the issue.
#mixin clearfix {
&::after{
content: "";
display: table;
clear: both;
}
}

I'm switching divs from float:left to inline-block and don't know why some of the divs are displacing, like they have some invisible border or something.
Here are with float:left https://jsfiddle.net/f7op4dze/
div{
background-color: red;
width: calc(25% - 40px);
height: 50px;
float:left;
margin:0 20px;
}
And here with inline-block https://jsfiddle.net/dfdxa5hc/
div{
background-color: red;
width: calc(25% - 40px);
height: 50px;
display:inline-block;
margin:0 20px;
}
There's a space automatically added with inline elements and this space is applied to inline-block as well.
If there's no whitespace (either a space or a return) between the elements in your markup, the inline-block elements will be rendered without a space.
The easiest way to do this and still retain optimal formatting is using comment tags in between the <div> elements like so:
https://jsfiddle.net/orvn/wd0ynq98/2/
<section>
<div></div><!--
--><div></div><!--
--><div></div><!--
--><div></div>
</section>
As one possible option to fix the problem, set the font-size of the parent to 0.
section { font-size: 0; }
You can restore the font on the child elements:
div { font-size: 16px; }
Demo: https://jsfiddle.net/dfdxa5hc/3/
For an explanation and other possible solutions, see my answer here:
inline-block boxes not fitting in their container
There is (finally) a CSS only solution to this problem
section {
display: table;
word-spacing: -2em;
width: 100%;
}
div {
display: inline-block;
word-spacing: normal;
}
When I set the padding size for input field it automatically changed the size. It becomes bigger.
.container{
width: 150px;
}
.item label{
display: block;
width: 100%;
margin-bottom: 10px;
}
.from-item{
width: 100%;
}
input[type="text"]{
width: 100%;
padding: 5px;
}
JSFfiddle
You should think about putting this in your CSS:
* { box-sizing: border-box }
This alters the box model such that padding will not add to the size that an element occupies on the screen. It is, to my mind and the mind of many others, a much better model to work with:
http://www.paulirish.com/2012/box-sizing-border-box-ftw/
General info on the box model: http://css-tricks.com/the-css-box-model/
You can use box-sizing:border-box to solve your problem, but it is a css3 property. Thus incompatible with old browsers.
Another way to achive this is put a wrapper div around input & give padding to it.
<div class="ibox"><input type="text" class="from-item"></div>
.ibox{
padding: 5px;
}
input[type="text"]{
width: 100%;
}
Here is Demo link http://jsfiddle.net/aq8mP/1/
So I'm trying to build a pure CSS responsive square (well actually I'm trying to build a circle but that's easy once I've got the square.)
In other words:
I want a div that has a height that is a percentage of the body and a width that is equal to that (or vice versa).
The div also needs to have another div inside it which can contain content and overflow: auto.
Lastly, the div can never exceed the height (or width) of the body or viewport.
So far, I have got some solutions working partially (i.e. in portrait but not landscape) using a 1px transparent .gif as an img to fill out a wrapper div. Not ideal semantics but I don't see how this can be done without it.
<div class="wrap">
<img src="http://www.neurillion.com/p/35/static/media/images/1x1t.gif" />
<main>
<div class="content">
<h2>Title</h2>
<p> Lorem... etc. </p>
</div>
</main>
</div>
Here are my CSS solutions and what is wrong with them:
This works except it exceeds the height of the body in landscape (max-height in any of the elements does not solve this):
.wrap {
background: blue;
margin: 10% auto;
width: 70%;
position:relative;
text-align:center;
}
.wrap img {
border: 1px solid black;
height: auto;
width: 100%;
}
main {
background: red;
display: block;
border-radius:50%;
height: 100%;
width: 100%;
position: absolute;
top:0
}
main div {
background: green;
overflow: auto;
display:inline-block;
height:70%;
width: 70%;
margin-top:15%;
}
Codepen
Next I added a landscape media query to swap around the height and width values. Same problem.
#media(orientation:landscape) {
.wrap {
margin: auto 10%;
height: 70%;
width: auto;
}
}
Codepen
At this point I started looking into .wrap's parent elements , namely the body and html. (Resource on the difference between them.) I added height and max-height: 100% to both of them, but no joy. I've also tried adding another div container as I thought it might be easier to control the height, but that doesn't seem to be doing much either.
And now I'm pretty much out of options. I'm fairly sure the solution is something to do with the html and body elements and the way they are so eager to expand vertically but I'm not really sure how else to stop them doing so.
Any help much appreciated.
You can use vw, vh and vmin to scale the square:
Demo: http://jsfiddle.net/r9VQs/
CSS (changed part only):
.wrap {
background: blue;
margin: 0 auto;
max-width: 90vh;
max-height: 90vh;
position:relative;
text-align:center;
}
You can also use vmin (which gives better results but is less well supported) and forego the image:
Demo: http://jsfiddle.net/r9VQs/2/
CSS:
.wrap {
background: blue;
margin: 0 auto;
width: 90vmin;
height: 90vmin;
position:relative;
text-align:center;
}
vh, vw and vmin are units equivalent to 1% of their respective viewport dimensions (vh is viewport-height, vw is viewport-width and vmin is whichever has a smaller value).
Please see http://caniuse.com/#feat=viewport-units for browser support.
I am having an issue with line-height that I cannot quite get my head around.
The following code will center an image within a div:
CSS
.bar {
height: 800px;
width: 100%;
line-height:800px;
background-color: #000;
text-align: center;
}
.bar img {
vertical-align: middle;
}
HTML
<div class="bar">
<img src="http://27.media.tumblr.com/yHWA4oxH870ulxnoH7CkOSDR_500.jpg" alt="Foo Image" />
</div>
However, if I change the line height to 100%, then the line height does not take effect (or at least does not become 100% of the div).
Example jsfiddle
Does anyone know what I am doing wrong?
line-height: 100% means 100% of the font size for that element, not 100% of its height. In fact, the line height is always relative to the font size, not the height, unless its value uses a unit of absolute length (px, pt, etc).
I know this question is old, but I found what for me is the perfect workaround.
I add this css to the div that I want to center:
div:before {
content: "";
display: inline-block;
height: 100%;
vertical-align: middle;
}
This works every time and it is clean.
Edit:
Just for completion's sake, I use scss and I have a handy mixin that I include on every parent who's direct children I want to have vertically centered:
#mixin vertical-align($align: middle) {
&:before {
content: "";
display: inline-block;
height: 100%;
vertical-align: $align;
// you can add font-size 0 here and restore in the children to prevent
// the inline-block white-space to mess the width of your elements
font-size: 0;
}
& > * {
vertical-align: $align;
// although you need to know the font-size, because "inherit" is 0
font-size: 14px;
}
}
Full explanation:
div:before will add an element inside the div, but before any of its children. When using :before or :after we must use a content: declaration otherwise nothing will happen, but for our purpose, the content can be empty. Then we tell the element to be as tall as its parent, as long as its parent's height is defined and this element is at least inline-block. vertical-align defines the vertical position of self related to parent, as opposed to text-align that works differently.
The #mixin declaration is for sass users and it would be used like this:
div {
#include vertical-align(middle)
}
When you use percentage as the line-height it is not based on the div container, rather its based on the font-size.
line-height: 100% would be an easy way to vertically center elements, if it was calculated in relation to the container, but that would be too easy, hence it doesn't work.
So instead, it is just another way of saying line-height: 1em (right?)
Another way of vertically centering an element would be:
.container {
position:relative;
}
.center {
position:absolute;
top:0; left:0; bottom:0; right:0;
margin: auto;
/* for horiz left-align, try "margin: auto auto auto 0" */
}
might not be pretty, but it's working, and its semantic;
<div class="bar" style="display: table; text-align: center;">
<img style="display: table-cell; vertical-align: middle;" src="http://27.media.tumblr.com/yHWA4oxH870ulxnoH7CkOSDR_500.jpg" alt="Foo Image" />
</div>
display: table-cell gives an element the unique table ablillity to align verticaly (atleast i think its unique)
This is a very late answer, however in modern browsers, assuming that the parent element is 100% of the screen height as well, you can use the vh viewport unit.
FIDDLE
line-height: 100vh;
Browser support
A more modern approach is to use flexbox for this, it is simpler and cleaner. However, flexbox is an entirely different paradigm from what inline-block, float or position used to be.
To align items inside .parent you do:
.parent {
display: flex;
align-items: center;
}
That is about it. Children of flex parents are automatically converted to flex child items.
You should read more about flexbox, a good place to start is this cheat sheet: https://css-tricks.com/snippets/css/a-guide-to-flexbox/
This is the modern solution in which you need to set the following CSS in the container div or outer div.
.outer-div {
display: flex;
justify-content: center;
align-items: center;
}
Another following solution may be applied to the element which you want to make centered vertically. Note that the outer or container div should be
.inner-div {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%,-50%);
text-align: center;
}
Note that the outer or container div position should be relative.
This solution works in IE9 and above. First we set the child's top position to 50% (middle of the parent). Then using translate rule, shift the child up by a half of its actual height. The main benefit is that we don't need to define child's height, it's calculated by the browser dynamically. JSFiddle
.bar {
height: 500px;
text-align: center;
background: green;
}
.bar img {
position: relative;
top: 50%;
transform: translate(0, -50%);
}
You can set line-height based on that element height. If the element height 200px means you need to set line height to 200px to center the text.
span {
height: 200px;
width: 200px;
border: 1px solid black;
line-height: 200px;
display: block;
}
<span>Im vertically center</span>
I want to set vertical alignment of image inside a div. I use img { vertical-align:middle}
but it is not working.
Using the line-height property will solve the problem:
<style>
.someclass {
width: 300px;
height: 300px;
text-align: center;
line-height: 300px;
border: dotted;
}
.someclass img {
margin: auto;
vertical-align: middle;
}
</style>
<div class="someclass">
<img src="someimg.jpg" border="0" alt="">
</div>
This is a solution that doesn't require JavaScript (as my previous solution did).
You can achieve what you want by assigning display: table-cell to the containing div. Here's an example: http://jsbin.com/evuqo5/2/edit
I feel I must warn you that you will need to test this in every browser you intend to support. Support for the table-cell value is fairly new, particularly in Firefox. I know it works in Firefox 4, but I don't know about any of the 3.x iterations. You'll also want to test in IE (I've only tested in Chrome 10 and Firefox 4).
The CSS:
div#container {
width: 700px;
height: 400px;
position: relative;
border: 1px solid #000;
display: table-cell;
vertical-align: middle;
}
div#container img {
margin: 0 auto;
display: block;
}
You won't need the div#container img styles if you don't also want to horizontally align the image.
If you're trying to do what I think, vertical align isn't going to work; you'll need to use positioning.
In general, position the container relative, and then position the image absolute, with top and left set to 50%, and then move the image back to the center by setting negative margins equal to half the width / height.
Here's a working example: http://jsbin.com/evuqo5/edit
Basic CSS is this:
#container { position: relative; }
#container img {
position: absolute;
left: 50%;
top: 50%;
margin-top: /* -1/2 the height of the image */
margin-left: /* -1/2 the width of the image */
}
See this awser: How to vertical align image inside div
If you want to align horizontally also, add the right and left, like this:
div {
position:relative;
}
img {
position:absolute;
top:0;
bottom:0;
left:0;
right:0;
margin:auto;
}
The following post has some useful references:
Text Alignment w/ IE9 in Standards-Mode
Also, depending on which version of IE you are testing against, you may end up needing some browser-specific hacks or some jQuery/JavaScript code.
If you have to, use a one-row-one-cell table and take advantage of the vertical-align property. This is brute-force, not overly semantic, but it works.
If you set the div display attribute to table-cell then vertical-align: middle; will work.
The vertical-align rule only affects table cells or elements with display: table-cell.
See this article from SitePoint for a detailed explanation.
