Example of problem http://img638.imageshack.us/img638/3733/97914817.jpg
I'm trying to recode one of my older forms. It was filled with tables that I want to replace with CSS. However I'm having trouble having text and a form element aligned vertically together. As the picture shows the text defaults to starting at the top instead of in the middle. The blue highlights around the row is dreamweavers interpretation / selection of what is going on.
I have label and input divs, both floated left, inside a div called #light, which is inside a general container. This is what my css code looks like:
#contentBox{
width: 600px;
float: left;
background-color: #e2e2e2;
overflow: auto;
border-color: #c5c5c5;
border-width: 1px;
border-style: solid;
font-size: 12px;
}
#light {
float: left;
width: 500px;
padding: 15px;
background-color: #e2e2e2;
margin: 7px;
border-color: #c5c5c5;
border-width: 1px;
border-style: solid;
vertical-align: middle;
}
input {
float: right;
width: 20em;
}
label {
float: left;
text-align: right;
vertical-align: baseline;
}
Any idea what the problem is? I've tried swapping around the vertical-align in different divs, floating in different directions, getting rid of the label but I just end up with more problems rather than less.
You cannot use vertical-align on elements unless they are table cells (or displayed as such) as this article explains. Set line-height to the element height if you've only got one row of text.
Usually, to solve that problem, I use the line-height property:
Ex:
div{width:600px;font:normal normal 12px/30px Arial, Helvetica, sans-serif;}
This will set the font to 12px, and the line-height to 30px, keeping the font vertically align within the 30px of its line.
Vertical alignment of text can be incredibly annoying or incredibly easy.
If the size of all the involved elements are known, your best bet is to set manual padding/margins on the text itself to make sure it's aligned.
If the content you want to center vertically is dynamic, this is your best bet.
Not sure, but your input tag is set to "float:right", so its height won't be taken into account by the parent. Hence, the height of the parent is actually probably the height of the label (I suspect dreamweaver is not interpreting correctly what browsers do.) Try to remove the float on the input tag and see if it makes a difference.
Vertical alignment can be applied only to inline elements.
The best solution is to modify your HTML and make it like in this examples
You could go for a 'cheap' solution and apply a padding-top to the label divs.

I'm trying to decrease the distance between the text in the h1 element and the border to the right so it looks like a small vertical line which separates it from the following text.
This is what my current css looks like:
.test{
border-right: 2px solid black;
padding-right: 0px;
}
The right border still appears very far on the right although I thought through setting the padding to 0px at the right it should appear directly next to the text.
I guess this is a pretty dumb question, I am still a beginner!
Thanks in advance
h1 elements are display: block by default (with width: 100%), which means they stretch to the full width of their container.
If you want to have the element only be as wide as it needs to be, make it display: inline-block instead (and then use padding, as you've identified, to determine the distance between the end of the text and the right border):
.test{
border-right: 2px solid black;
padding-right: 0px;
display: inline-block;
}
<h1 class="test">This is a test</h1>
h1 elements are display:block by default, 100% width by default. Try changing width:300px or display:inline-block.
I have a very simple setup:
<button>
Lorem
</button>
<input type="text" value="Ipsum">
with both elements next to each other using display: inline-block:
button, input{
height: 34px;
line-height: 34px;
display: inline-block;
box-sizing: border-box;
vertical-align: baseline;
padding: 0;
margin: 0;
border: 1px solid green;
font-size: 14px;
}
Example here: http://jsfiddle.net/j02ypo0v/
As you can see, the two elements are not perfectly aligned (off 1px).
I know, I could easily solve this by changing vertical-align to middle, but I want to understand why this offset is present in the first place.
IMO, it doesn't make any sense that the two elements are not perfectly vertically aligned since they share all CSS attributes (especially height, line-height, display and vertical-align).
Can anybody explain me where the 1px offset is coming from?
The baseline alignment is to do with the positioning of the text rather than the positioning of the element as a whole. If we zoom in on the button and input elements and add a straight line below the text, you'll see that the text in both elements is in fact vertically aligned at the same position:
I can't tell you what the exact cause of the problem is, but what I do know is that if you reduce the line-height to 32px or increase it to 35px the two elements become in line with each other whilst keeping the text in line as well:
My guess is that there's a difference in calculation on the browser side of things when using a line-height of 34px and a font-size of 14px between a button and input element as in your example, as if we do change the vertical-align to middle as your question suggests the text is no longer in line:
It's because a button is replaced inline element.
MDN says about line-height:
On non-replaced inline elements, line-height specifies the height that
is used to calculate line box height. On replaced inline elements such
as buttons or other input element, line-height has no effect.
You need to remove the following:
padding: 0, since the input will naturally have padding
height: 34px, since you already use the line-height
Find the results here: jsfiddle.net
button, input{
line-height: 34px;
border: 1px solid green;
font-size: 14px;
display: inline-block;
box-sizing: border-box;
vertical-align: baseline;
margin: 0;
}
I have added a yellow div container so it's easier to see.
I am trying to vertically align a div and an input:
<div id="a">
Button
</div>
<input type="text" id="b" placeholder="text">
They both share the same styles:
#a, #b{
box-sizing: border-box;
vertical-align: baseline;
padding: 0;
margin: 0;
outline: none;
font-size: 10px;
line-height: 10px;
font-family: serif;
border: none;
height: 30px;
width: 100px;
background: green;
display: inline-block;
border: none;
}
However, they are not vertically aligned:
Sample
How is that possible?
Please note: This is an abbreviated example from a bigger project where I have to use vertical-align: baseline. It is not possible to change that value and I do not want to use any hack like adding a margin-top. I want to understand why the vertical-align behaves this way and try to find a clean solution.
Since your height has a static value, you can use line-height: 30px; CSS property to force the alignment you want.
JSFiddle
Cumbersome explanation:
Your div's baseline is 10 px (see line-height property), while your element's height is 30 px. Text inside input element is vertically centered by default, baseline, in your case, 30px. So basically, browser tries to center elements by it's baseline, which is different for the elements, thus causing the first element, with a smaller baseline value, to be pushed down.
You need to add float: left to make it align on vertically.
I want to know is there a way to centre text vertically without the use of a container element. something which is responsive.
EDIT
the only value I would know is the height of the h3 element, nothing more,
content will appear underneath some as etc
CSS
h3 {
height: 140px;
padding-top: 80px;
min-height: inherit;
border: 1px solid black;
text-align: center;
}
HTML
<h3>TEST</h3>
Here is an example of what i want to achieve
codepen test
Line-height is a beautiful thing, especially if its just text. And if you want to be responsive:
h3 {
background-color: transparent;
height: 40vh;
line-height: 40vh;
min-height: inherit;
border: 1px solid black;
text-align: center;
}
There is no easy way to do this. I have come up with a couple techniques over the years.
You have 80px in padding and a height of 140px for a combined height of 240px. If you know that the text will not exceed one line you can do it using line-height.
h3{
line-height:240px;
...
}
Another way is to use padding if you know the height of your text.
h3{
font-size: 20px;
line-height:20px;
padding:110px 0;/* (240-20)/2 */
...
}
note: I don't like the display: table-cell hack and have yet to need it. Why move away from a table based layout if you're just going to tell the browser to treat the element as a table?
Add to your code:
display: table-cell;
vertical-align: middle;
You will need to adjust your padding. That should work.
This article provides 6 different methods and their associated pros and cons; it explains it far better than I could here. The solutions provided as answers here are good, but the article really covers niche cases and allows you to choose the best method to fit your needs.
http://www.vanseodesign.com/css/vertical-centering/
You're going to have a containing element, regardless. It's just that the body might be the container.
You could do this:
body {
height:100%;
display: table;
margin: 0px;
padding: 0px;
}
h3 {
display: table-cell;
vertical-align: middle;
}
OR...
body {
height:100%;
margin: 0px;
padding: 0px;
}
h3 {
position: relative;
top: 50%;
}
edit - removed width specific styles as it has nothing to do with the solution. Thanks to Jason for the margin/padding set to 0px to remove ugly scrollbars. Jason also noted that this solution did not work for Chrome unless the "body" element in the styles was changed to "html, body", but I was not able to replicate this problem using Chrome version 35.0... For good measure I also opened a test page in Safari and Firefox and they also worked as expected.
edit^2 - Figured out the problem Jason saw. If you use the html5 doctype, then, yes, you will have to include the html element with the body style. This also makes the scrollbar reappear in the relative position solution. So that's fun. I will leave this up for the purpose of saving frustration in the future, but I would check out the link provided in Jason's solution.

How can I vertically center text in a dynamically height div?
Firstly my CSS skills are... a work in progress. But I have got so far in as to successfully have a bunch of list items arranged in a grid. http://jsfiddle.net/ashanova/Y4SR3/2/
What I'd like to do now is centre the list items. I have tried to replace float with inline but it causes the width and height of each item to collapse. I would also like to centre the text horizontally and vertically within each list item as well, ideally ellipsisizing (not a word) overflow text. As one last specification I would like to only modify CSS to the ul and its children if thats possible.
While the language gets a little unclear when you're dealing with multiple parent and child elements, and centering (/middling) on 2 axes, I think that if the other answers aren't what you're looking for, you might actually want display: table-cell.
Check this fiddle.
If you give your li elements display: table-cell, text-align: center and vertical-align: middle, I think the text will arrange itself appropriately. Unfortunately, table-cell elements don't accept margin, so I added a 10px border instead.
In order to accomplish truncation of text that overflows and the insertion of an ellipse, you'll need to use some kind of javascript.
UPDATE
Having learned more about what you're after through the many other answers and comments, I've come up with a better solution here: http://jsfiddle.net/crowjonah/jx8sD/
What you need to do is insert <a class="list-item"> tags inside the li elements, and use this CSS:
.tile li {
background-color: white;
display: block;
float: left;
margin: 10px;
overflow: hidden;
}
.tile li a.list-item{
display: table-cell;
vertical-align: middle;
height: 75px;
text-align: center;
width:75px;
}
Text-align: center will align your list items to the center. Vertical-align: text-top will align items to the center vertically.
vetical-align will not actually do the job in this case. I wish it were that simple.
This aricle will give you some insight into the problem and will help you solve it:
Understanding vertical-align, or "How (Not) To Vertically Center Content"
This will do what you want. Borders on inline-block items are a pain, so I'm using a border to make it look right.
.tile li {
background-color: white;
display:inline-block;
border: 10px solid red;
width: 75px;
height: 75px;
text-align:center;
display:table-cell;
vertical-align:middle;
overflow: hidden;
}
