The principle and implementation of writing pure CSS pop-up menu By shawl.qiu
Abstract:
This article introduces the use of CSS to write multi-style pop-up menus suitable for Opera, Firefox, and IE
## #Description:
The key point of writing a CSS pop-up menu is to display the hidden label when the mouse moves over the target.
The label to be hidden is hidden using the display:none; attribute.
Trigger display Hidden tags mainly use the :hover attribute, and use display:block; to display hidden tags.
But because browsers do not support CSS consistently.
For Opera or Firefox, we can write a pure CSS menu , they support the :hover attribute of any tag.
For IE browser, :hover only works on the a tag, but we can use the script's onmouseover, onmouseout to simulate the :hover attribute of other tags.
Therefore Writing a CSS pop-up menu suitable for IE requires the use of a few scripts.
