Is there a preferred method for centering elements using CSS?
<div style="position: absolute; left: 50%;">
<div style="position: relative; left: -50%">
Centered content
</div>
</div>
or simply
<div style="text-align:center">
Centered content
</div>
?
Edit: Ah, so it seems that "text-align:center" is better suited for inline elements while "margin: 0 auto" is recommended for block elements. Good to know.
The first example is quite unique, not a common sight. Using text-align:center can be reliable for centering inline elements, but when that doesn't work, my go-to is margin: 0 auto;
<div style="text-align:center">
Centered content
</div>
Alternatively,
<div style="margin: 0 auto;">
Centered content
</div>
As BenM mentioned, margin: 0 auto; is great for centering display:block elements with a specified width.
So what exactly does margin: 0 auto; do? Well, setting the top and bottom margins to 0 and using auto calculates and applies equal left and right margins to achieve centering for any element with this style rule.
To optimize spacing, assign a width to the element and then define margin: 0 auto.
Here's an illustration:
div {
width: 700px;
margin: 0 auto;
}
To center an inline element, apply text-align:center on the parent container.
For a block element, use margin: 0 auto;
p {
text-align:center;
}
div {
width: 100px;
margin:0 auto;
}
When you use text-align: center; it will only center the text within the div element. To center the entire block element, you have other options such as adding margin: 0 auto; or positioning it with either position: absolute or position: relative depending on where you want to center it (parent element/body, etc).
