Similar structure:

The code is as follows:

<p></p><ifram src="<a href="http://caibaojian.com"></iframe">http://caibaojian.com"></iframe</a>

First type: the transparent background is covered

When p uses a transparent background, no matter it is used (opacity or rgba format), except Chrome, other browsers will have p covered by iframe.

Solution:

p Use an opaque background or use a transparent background image.

Second type: z-index failure in ie8

In ie, introduce video into iframeVideoplay This will cause the z-index of p to be invalid, that is, no matter what the z-index of p is set to, it will be covered by the iframe. Source

Solution:

Add a parameter wmode=opaque to the iframe address. If the address is: http://caibaojian.com, then change it to: http://caibaojian.com? wmode=opaque.
