Following an example found over at CSS Tricks, I'm trying to center align content that is inside a circle container that is responsive. The example doesn't seem to be able to handle much content, and immediately breaks as soon as I enter more than a few lines of text.
Code Pen Example
Inside the circle I need to have a header and a paragraph. Is there any way to set a max width of this content so that it isn't placed outside the circle when it doesn't fit?
You can set top value accordingly in your .content code pen
Edit
Do this changes:
.content {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
display: table;
}
.content span{
display: table-cell;
vertical-align: middle;
text-align: center;
}
Now short text or long text that all will be centered now.

I am vertically aligning a div using Michał Czernow's technique posted on CSS Tricks:
HTML
<div class="block">
<div class="centered">
Unknown stuff to be centered.
</div>
</div>
CSS
/* This parent can be any width and height */
.block {
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.block:before {
content: '';
display: inline-block;
height: 100%;
vertical-align: middle;
margin-right: -0.25em; /* Adjusts for spacing */
}
/* The element to be centered, can
also be of any width and height */
.centered {
display: inline-block;
vertical-align: middle;
width: 300px;
}

This method works perfectly, however, if I have content that exceeds the height of the browser window, the content breaks outside of its div.
My question is this. Is there a way to keep height: 100%, but make height: auto for divs that exceed the browser height (if possible without js)?
Thanks in Advance!
min-height:100%? Seems like a simple solution unless I'm missing something.
I'm trying to center horizontally a divs in a div with 100% width. The div conteiner is "#post-area" and all divs inside, have a class ".post".
this is the link: http://bit.ly/VOqkhv
When resize the browser is possible to see that not work good, in fact, all divs are not centering with the menu. How can fid this? I tried also with margin: auto; but nothing .
Thank you so much in advance.
Set the 100% div to position:relative then the element you want to center to position:relative; margin: 0 auto;
That is because they are floating to the left. You can use inline-block instead.
Add text-align: center; to #post-area
Remove float: left; and add display: inline-block; vertical-align: top; text-align:left; to .type-post
I have a responsive element where it's width and height will both scale. Inside this I have some text which I want to center vertically.
How can I set the text's line-height to be the same as it's parent if I don't know the parent's height?
line-height: 100% is relative to the font's regular height so this doesn't help...
Here's another way to center an element vertically. I came across this technique some time ago. Basically it uses a pseudo element and vertical-align: middle.
.block::before {
content: '';
display: inline-block;
height: 100%;
vertical-align: middle;
margin-right: -0.25em; /* Adjusts for spacing */
}
/* The element to be centered, can
also be of any width and height */
.centered {
display: inline-block;
vertical-align: middle;
width: 300px;
}
Since it's 2019 already, you could also use flexbox to achieve this :)
To do so, add the following classes to the parent element:
display: flex;
flex-direction: column;
justify-content: center;
See this Fiddle
I'd try putting the text inside another element, of which you know (or set) the size. Then setting relative positioning to it, top, left 50% and negative left and right margins.
See this Fiddle
The only problem is that this relies on a known/fixed textblock. If the text is variable, I'm afraid you will have to resort to using Javascript..
Regarding hyperlinks:
I was having this problem regarding links in main menu. And since it was <a> in <li> tags I needed some surface for the links to be clickable/touchable(see touch target size).
So what I did was for the <ul> I set a fixed height(through it's parent in this case), the <li>-s are a percentage of it and the <a>-s have a min-height and line-height properties set to them and it's easy from there to set the top. The code:
.menu-header-main-container{
position: fixed;
top: 0;
bottom: 160px;
}
.menu-header-main-container ul.menu {
height: 100%; }
.menu-header-main-container ul.menu li {
height: 33.33%;
max-height: 110px; }
.menu-header-main-container ul.menu li a {
line-height: 40px;
min-height: 40px;
top: calc(50% - 20px);
position: relative; } }
You cannot set the line-height to 100% of the parent element's height with only CSS. Rather, you can use CSS to center an element vertically.
.parent {
height:150px;
position:relative;
border:1px solid #FDD;
}
.position-center {
position:absolute;
top:50%;
transform:translateY(-50%);
}
<div class="parent">
<span class="position-center">I am vertically centered element</span>
</div>
Wow, 2022 and I don't think we have a decent way to do this still. What I used to do and I think is the less painful idea is to use a table for layout. Tables will naturally center text vertically, or you can use "vertical-align"
<table style="width: 100%; height: 100%; text-align: center">
<tr><td>Your text</td></tr>
</table>
Not great, but at least you can center text without ever having to specify fixed heights.
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>
