In ie6, overflow and text-indent:-9999px fonts are hidden.

In ie6, overflow and text-indent:-9999px are hidden in the input value:

1. Use text-indent:-9999px. However, he has a limitation that it is only applicable to block-level element blocks. The input value does not work under ie6 and must be added to the input style: line-height: 0;
Font-size: 0;

For example:

. Sign_but1 {

Width: 110px;

Height: 42px;

Text-indent:-99999px;

Line-height: 0;

Font-size: 0;

Float: left;

Background: url (../images/login/images/login_but.png) no-repeat;

Border: none;

Margin: 15px 25px 0 0! Important;

Cursor: pointer;

}

Only in this way will the value in input be hidden as expected under ie6.
