Personal Note 1: usage of display and visibility

Source: Internet
Author: User

Some people will confuse the display and visibility attributes in CSS. They seem to be no different. In fact, the difference is great.

The visibility attribute controls whether the positioning element is visible. The values include visible (visible), hidden (hidden), and inherit (inherited). The default value is inherit. The difference between the visibility attribute and the display attribute is that when an element is hidden, the element defined by the visibility attribute retains the original display space.

For example, the following code:

<HTML>  

If we want to hide case 1 and Case 2 rush up to occupy the position of Case 1, we can use the following code to format Case 1:

#dis{    border:2px solid red;    width:100px;    margin:10px;    display:none;}

If you want to hide case 2 but leave its position blank, you can use the following code to format Case 1:

#dis{     border:2px solid red;     width:100px;     margin:10px;     visibility:hidden;}
