Issue
I am trying to center my tabs content vertically, but when I add the CSS style display:inline-flex
, the horizontal text-align disappears.
How can I make both text alignments x and y for each of my tabs?
* { box-sizing: border-box; }
#leftFrame {
background-color: green;
position: absolute;
left: 0;
right: 60%;
top: 0;
bottom: 0;
}
#leftFrame #tabs {
background-color: red;
position: absolute;
top: 0;
left: 0;
right: 0;
height: 25%;
}
#leftFrame #tabs div {
border: 2px solid black;
position: static;
float: left;
width: 50%;
height: 100%;
text-align: center;
display: inline-flex;
align-items: center;
}
<div id=leftFrame>
<div id=tabs>
<div>first</div>
<div>second</div>
</div>
</div>
Solution
Approach 1 -
transform
translateX
/translateY
:
Example Here / Full Screen Example
In supported browsers (most of them), you can use top: 50%
/left: 50%
in combination with translateX(-50%) translateY(-50%)
to dynamically vertically/horizontally center the element.
.container {
position: absolute;
top: 50%;
left: 50%;
-moz-transform: translateX(-50%) translateY(-50%);
-webkit-transform: translateX(-50%) translateY(-50%);
transform: translateX(-50%) translateY(-50%);
}
<div class="container">
<span>I'm vertically/horizontally centered!</span>
</div>
Approach 2 - Flexbox method:
Example Here / Full Screen Example
In supported browsers, set the display
of the targeted element to flex
and use align-items: center
for vertical centering and justify-content: center
for horizontal centering. Just don't forget to add vendor prefixes for additional browser support (see example). Remember the parent container will also need height (in this case, 100%).
html, body, .container {
height: 100%;
}
.container {
display: -webkit-flexbox;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;
justify-content: center;
}
<div class="container">
<span>I'm vertically/horizontally centered!</span>
</div>
Approach 3 -
table-cell
/vertical-align: middle
:
Example Here / Full Screen Example
In some cases, you will need to ensure that the html
/body
element's height is set to 100%
.
For vertical alignment, set the parent element's width
/height
to 100%
and add display: table
. Then for the child element, change the display
to table-cell
and add vertical-align: middle
.
For horizontal centering, you could either add text-align: center
to center the text and any other inline
children elements. Alternatively, you could use margin: 0 auto
, assuming the element is block
level.
html, body {
height: 100%;
}
.parent {
width: 100%;
height: 100%;
display: table;
text-align: center;
}
.parent > .child {
display: table-cell;
vertical-align: middle;
}
<section class="parent">
<div class="child">I'm vertically/horizontally centered!</div>
</section>
Approach 4 - Absolutely positioned
50%
from the top with displacement:
Example Here / Full Screen Example
This approach assumes that the text has a known height - in this instance, 18px
. Just absolutely position the element 50%
from the top, relative to the parent element. Use a negative margin-top
value that is half of the element's known height, in this case - -9px
.
html, body, .container {
height: 100%;
}
.container {
position: relative;
text-align: center;
}
.container > p {
position: absolute;
top: 50%;
left: 0;
right: 0;
margin-top: -9px;
}
<div class="container">
<p>I'm vertically/horizontally centered!</p>
</div>
Approach 5 - The
line-height
method (Least flexible - not suggested):
In some cases, the parent element will have a fixed height. For vertical centering, all you have to do is set a line-height
value on the child element equal to the fixed height of the parent element.
Though this solution will work in some cases, it's worth noting that it won't work when there are multiple lines of text - like this.
.parent {
height: 200px;
width: 400px;
background: lightgray;
text-align: center;
}
.parent > .child {
line-height: 200px;
}
<div class="parent">
<span class="child">I'm vertically/horizontally centered!</span>
</div>
