TLDR

To center a <div> horizontally using CSS, simply give it a proper width and set both margin-left and margin-right to auto:

.centered { width: 50%; /* Feel free to adjust accordingly */ margin: 0 auto; /* Presto! Magic trick performed */ }

Use this class in your <div>:

<div class="centered">Centered content</div>

This quick trick often does the job for block elements with a fixed width.

Centering strategies for more complex cases

Inline-block for unpredictable content width {

Dealing with dynamic content? Use display: inline-block to keep it centered:

.centered-inline { display: inline-block; text-align: center; }

Then wrap your <div> with a parent div:

<div id="wrapper" style="text-align: center;"> <div class="centered-inline">Dynamic centered content</div> </div>

Legacy browser hacks

If you're dealing with IE6 (yes, it's a dinosaur but some still use it), use a <div> wrapper:

.wrapper { text-align: center; } .centered-legacy { display: inline-block; text-align: left; /* Because left is the new center */ }

Flexbox comes to the rescue

Here's how to use Flexbox and come off like a pro:

.flex-container { display: flex; justify-content: center; /* The Jedi way of centering */ }

And in your HTML:

<div class="flex-container"> <div>Centered content</div> </div>

The Transformer way

Last but not least, for exceptional precision, use a CSS transform:

.transform-centered { position: relative; left: 50%; transform: translateX(-50%); /* Because we care about precision */ }

The transform method becomes helpful when width varies and 'adapting to content' is your mantra.

Extra tips and tricks to make it even better

Min-width for flexible stability

You can use min-width to prevent the <div> from becoming too wimpy, while melting hearts with a stable yet flexible layout. Browser support is a must-check, though.

Making things visible with background color

Light up the development stage with background-color: #eee; on your <div> as it works like a superstar on Broadway, making layout issues easier to spot.

Class act for the maintenance team

Cook up a specific class (let's say .centered) for your centering styles. This keeps your CSS squeaky clean and easy to maintain, and inline styles on a diet.

HTML5/CSS3 treats, but with mindfulness

Always remember to include polyfills for HTML5/CSS3 features and do a rain dance praying older browsers support it. Double-check the need for vendor prefixes with properties like transform.

Responsive approach with vw

Come across as a genius with responsive units like vw (viewport width). Let your design sip on this responsive potion for fluid centering, but be careful not to spill it over on smaller screens!
