Why Doesn\'t My Iframe Center Horizontally?

How to Center an Iframe Horizontally

The original question highlighted a scenario where an iframe was not aligning centrally within its parent div. The cause of this issue and the solution are outlined below.

Iframe Does Not Center Properly

In the provided HTML and CSS code, the iframe is rendered alongside a div using similar properties for width, height, margin, and background color. However, the iframe does not align centrally like the div. This is because iframes are inherently inline elements, meaning they occupy space only as wide as their content.

Solution: Add 'display:block;'

To centrally align an iframe, it is necessary to convert it from an inline element to a block element. This can be done by adding the following CSS property to the iframe:

<code class="css">display: block;</code>

Additional Tweaks

Additionally, to ensure proper alignment and prevent any border from displaying on the iframe, the following CSS can be applied:

<code class="css">border-style: none;</code>

Updated CSS:

<code class="css">div, iframe {
    width: 100px;
    height: 50px;
    margin: 0 auto;
    background-color: #777;
}

iframe {
    display: block;
    border-style: none;
}</code>

By implementing these changes, the iframe will now be centered horizontally within its parent div.
