How to Horizontally Center a Div in CSS

To horizontally center a <div> element in CSS, you can use one of the following methods:

Method 1: Using margin: auto;

You can use the margin property with the value auto to horizontally center a <div>. Here's how you can do it:

<div style="margin: 0 auto">Centered div</div>

In the above example, we set the margin property of the <div> to 0 auto. The 0 value for the top and bottom margins ensures that the <div> doesn't have any vertical spacing. The auto value for the left and right margins automatically distributes the remaining space equally on both sides, effectively centering the <div> horizontally.

Method 2: Using flexbox;

Another way to horizontally center a <div> is by using flexbox. Here's an example:

<div style="justify-content: center">Centered div</div>

In the above example, we set the display property of the <div> to flex to create a flex container. The justify-content property with the value center aligns the flex items (in this case, the <div>) along the horizontal axis, effectively centering it.

Best Practices:

- It's recommended to use CSS classes instead of inline styles for better maintainability and reusability. For example:

    .centered {
        margin: 0 auto;
        display: flex;
        justify-content: center;
    }


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

- If you want to center a <div> both horizontally and vertically, you can use the align-items property in combination with justify-content. For example:

    .centered {
        display: flex;
        justify-content: center;
        align-items: center;
    }


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

- If you need to support older browsers that don't fully support flexbox, you can use a combination of display: table and text-align: center to achieve horizontal centering. However, this method is less flexible compared to flexbox. Here's an example:

    .centered {
        display: table;
        margin: 0 auto;
        text-align: center;
    }


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

Alternative Ideas:

- Another approach to horizontally center a <div> is by using the position property. You can set position: absolute on the <div> and then set left: 50% and transform: translateX(-50%) to center it. However, this method requires the parent container to have a non-static position (e.g., position: relative).

    .parent-container {
        position: relative;
    }

    .centered {
        position: absolute;
        left: 50%;
        transform: translateX(-50%);
    }


<div class="parent-container">
    <div class="centered">Centered div</div>
</div>

- If you only need to center a single line of text within a <div>, you can use the text-align property instead. For example:

<div style="text-align: center"><a href="https://www.squash.io/centering-text-with-css-tricks-and-techniques/">Centered text</a></div>
