How to vertically align floating divs to the bottom? - css

Because examples rule: http://jsfiddle.net/rudiedirkx/wgue7/
How do I get the bars to the bottom instead of the top? Now they're sticking to the top of the container (#bars) but I want them sticking to the bottom.
As you can see, I don't know the height of the highest bar, so I don't know the height of the container.
These q+a don't help: Vertically align floating divs, Vertically align floating DIVs
Should be simple, right? If it helps: it only has to work in decent browsers.
PS. Number of bars is variable (not in the example) and their heights are. Only their widths are static. Positioning absolute won't help, because the container div doesn't have measurements.

This will do the trick:
#bars {
display: table-cell;
border: solid 1px black;
}
#bars > div {
display: inline-block;
vertical-align: bottom;
width: 5px;
background-color: #999;
margin-left: 2px;
}
#bars > div:first-child {
margin-left: 0;
}
It uses display: table-cell; on the parent div, which by default has vertical-align: baseline; applied. This changes the need for float: left; on the child divs and allows us to use display: inline-block;. This also removes the need for your CSS clear fix.
EDIT - Per #thirtydot's comments, adding vertical-align: bottom; to the child divs removes the gap at the bottom.
Therefore, I changed CSS above and jsFiddle. I kept the display: table-cell; so that the parent div wraps the child divs with 0 padding and looks nice and snazzy!

FLEXBOX! Flexbox is the most bestest.
Example: http://jsfiddle.net/rudiedirkx/7FGKN/
Flexbox makes this ridiculously simple (and not to forget correct):
#container {
display: flex; /* or inline-flex */
flex-flow: row nowrap; /* is default: columns along the main-axis (row) and no wrapping to next lines */
align-items: flex-end; /* bottom */
}
#container > div {
/* margin etc here, but nothing layoutish */
}
That's it Two lines of CSS: display: flex and align-items: flex-end.

CSS flexible padding-divs with centered text inside, max-padding

image
codepen
hello, i need help with css styling.
i'm trying to have a responsive main menu,
but cannot figure out a way to keep the text horizontally-centered within the item boxes, once these start to shrink due to low viewport width.
.container {
display: flex;
justify-content: center;
}
this allows for flexible horizontally-centered menu items
.item {
padding: 5px 30px;
text-align: center;
}
what happens is that once the boxes start to shrink, the left padding is preserved while the right one is being "overflow-hidden", which puts the text off-center with respect to their .item containers.
i need the text to stay centered within the item box, while keeping some fixed horizontal padding around the text (enlaring the item box) when width is sufficient.
this is what i tried, but unsurprisingly it didn't work :-)
.item {
width: calc(auto + 60px);
text-align: center;
}
thanks for help
What about using line-height?
Like this http://jsbin.com/capixobihe/1/
#menu ul li {
padding:6px;
margin:0 5px;
font-family:Arial;
line-height:30px; /* <--- Set this */
background-color:#FFF;
display:inline-block;
}

Set line-height as a percentage relative to the parent element

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.

CSS floated elements not sitting next to each other

Please take a look at: http://jsfiddle.net/yCrA8/
The blue sidebar should float next to red middle box but instead it's clearing it and sitting below...
How do I fix this? I can't set a width for the .Middle div because it has content that needs to flow outside of the browser view and be scrollable.
Cheers
See: http://jsfiddle.net/thirtydot/yCrA8/4/
One way is to use display: inline-block and white-space: nowrap.
Remove float: left from .Sidebar and .Middle, then add this:
.MainContent {
white-space: nowrap
}
.Sidebar, .Middle {
white-space: normal;
vertical-align: top;
display: inline-block;
/* if you need ie6/7 support */
*display: inline;
zoom: 1
}
#Camernon; there is a reason why your middle div is not wrap because you did not define width to your middle div for this you can define width your middle & it's parent div
CSS:
.Middle
{
background:red;
width:9125px;
float:left;
}
.MainContent
{
margin: 20px;
width: 9330px;
}

line-height as a percentage not working

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>

Flowing items horizontally w/ center alignment within a container

My dilemma is this (and should be simple, I suspect): I have a container and a set of items (both divs). The following CSS applies:
.container {
float: left;
width: 100%;
}
.item {
margin: 32px;
text-align: center;
position: relative;
float: left;
}
The .item itself is a container that could have almost any set of arbitrary elements, but they need to be center aligned inside of it (in my case, it typically contains a thumbnail image and a small caption of text beneath it). While the above CSS allows each .item to flow horizontally the way I like, I can't figure out how to make the whole set center aligned (as opposed to flowing from left to right like it does now).
edit
Change .item { display: block; } to .item { display: inline-block; }, take away .item { float:left; } and add text-align: center; to .container
You can see it here: http://jsfiddle.net/JMC_Creative/RQrRb/
You could also put an .inner div with width:75%; margin: 0 auto; and then put your .items in that, if you are looking to have some space on the sides.
You'll want to take a look at this tutorial from Mozilla. It can be center aligned by just setting the parent container to text-align:center;
Cross Browser Inline Block
.container {
width: 100%;
}
.item {
margin: 32px;
text-align: center;
}
