In the given HTML, the unordered list (
Solution 1: Using max-width and margin
ul { max-width: 400px; margin: 0 auto; }
This method sets a maximum width for the ul and applies equal left and right margins to automatically center it within the div.
Solution 2: Utilizing text-align with inline-block
.container { text-align: center; } ul { display: inline-block; }
This solution aligns the div using text-align: center and makes the ul an inline-block element. As inline-block elements respect the text-align property, the ul becomes centered.
Solution 3: Employing display: table and margin
ul { display: table; margin: 0 auto; }
This method involves setting the ul to display as a table, which causes it to behave as a block element and automatically center itself within the div.
Solution 4: Using position, left, and transform
.container { position: relative; } ul { position: absolute; left: 50%; transform: translateX(-50%); }
This approach positions the ul absolutely within the div, moves it 50% from the left using left: 50%, and finally shifts it back by 50% through transform: translateX(-50%).
Solution 5: Leveraging Flexbox
.container { display: flex; justify-content: center; }
With Flexbox, setting the container to display as a flexbox and specifying justify-content: center ensures that the ul is horizontally centered within the div.
These solutions provide various techniques to center a ul horizontally in a div, allowing you to select the most appropriate approach based on browser compatibility and desired behavior.
