The picture cannot be displayed or seen. Please write down what effect you want.

Where are the pictures? That ad? ? ?

You set the padding-top to 2px; the ul tag has default margin and padding values, set the other ones as padding: 2px 0 0;
The li style is not unified and the background style is overwritten. It can’t be displayed

The picture can’t be displayed. I can’t see it. Please write down what effect you want.
How can I display the picture here?

Sir, if you set up your ul and add an attribute: padding-left:0px; it will be OK
ul has its own padding value

about.css: 27 lines

.left_menu ul {background: white url('../image/left_menu_ul.gif') no-repeat;padding-top: 2px;padding-left: 0;}
