Why Doesn\'t `margin: auto;` Center Inline-Block Elements Horizontally?

margin:auto; in Inline-Block Elements

When applying margin:auto; to a div with inline-block display, it may not center the div horizontally as expected. This occurs because inline-block elements behave like inline elements, flowing along the page.

In the code provided:

Old Code (Works)

<code class="css">#container {
  width: 200px;
  ...
}</code>

The div is given a specific width, ensuring it fits within its parent container.

New Code (Doesn't Work)

<code class="css">#container {
  display: inline-block;
  ...
}</code>

Setting display: inline-block allows the div to shrink and grow depending on its content, leading to its improper alignment.

To center the div, the code requires:

Solution

1. Add text-align: center; to the containing element (.center in the example).

<code class="css">.center {
  text-align: center;
}</code>

This ensures that the inline-block div is centered.

<code class="html"><div class="center">
  <div class="MtopBig" id="container">...</div>
</div></code>
