Why the iframe is not centrally aligned like the div? How could I centrally align it?

Solution

Add display:block; to your iframe css.

OTHER TIPS

best way and more simple to center an iframe on your webpage is :

<p align="center"><iframe src="http://www.google.com/" width=500 height="500"></iframe></p>

where width and height will be the size of your iframe in your html page.

HTML:

<div id="all">
    <div class="sub">div</div>
    <iframe>ss</iframe>
</div>

CSS:

#all{
    width:100%;
    float:left;
    text-align:center;
}
div.sub, iframe {
    width: 100px;
    height: 50px;
    margin: 0 auto;
    background-color: #777;

}

If you are putting a video in the iframe and you want your layout to be fluid, you should look at this webpage: Fluid Width Video

Depending on the video source and if you want to have old videos become responsive your tactics will need to change.

If this is your first video, here is a simple solution:

<div class="videoWrapper">
    <!-- Copy & Pasted from YouTube -->
    <iframe width="560" height="349" src="http://www.youtube.com/embed/n_dZNLr2cME?rel=0&hd=1" frameborder="0" allowfullscreen></iframe>
</div>

And add this css:

.videoWrapper {
	position: relative;
	padding-bottom: 56.25%; /* 16:9 */
	padding-top: 25px;
	height: 0;
}
.videoWrapper iframe {
	position: absolute;
	top: 0;
	left: 0;
	width: 100%;
	height: 100%;
}

Disclaimer: none of this is my code, but I've tested it and was happy with the results.

The simplest code to align the iframe element:

<div align="center"><iframe width="560" height="315" src="www.youtube.com" frameborder="1px"></iframe></div>

You can put iframe inside a <div>

<div>
    <iframe></iframe>
</div>

It works because it is now inside a block element.

According to http://www.w3schools.com/css/css_align.asp, setting the left and right margins to auto specifies that they should split the available margin equally. The result is a centered element:

margin-left: auto;margin-right: auto;

You can try 

<h3 style="text-align:center;"><iframe src=""></iframe></h3>

I hope its useful for you
