# Nav

Margin-top: 50px;
Overflow: hidden;
Height: 1%;
Background: url (../images/nav-bg.png) repeat-x;
Text-transform: capitalize;

[Description]

Margin-top: 50px;

The distance between the navigation bar and the top of the page is 50px;

Overflow: hidden;
The content will be trimmed and the rest will be invisible.

Height: 1%;
The height is 1% of the parent element. If the parent element does not set a height value, it does not take effect. The actual height is determined by the internal element. Here, it is used with overflow: hidden; to eliminate some bugs in earlier IE versions.


Background: url (../images/line.gif) no-repeat center right;

Center the right side of the vertical line separator Image

Padding-right: 1px;

Fill 1px inside the right side, which is the position left for the vertical line to separate the image

Background: url (../images/nav-bg.png) repeat-x left bottom;

Left bottom is equivalent to 0-30px

 

[Technical points]

The size of the navigation bar in the list is determined by the layer-3 label. The top layer label is a, the height is 30px, the width is 20px + the text width is 20px, and the second layer is li, width = the width of a + 1px, the height of 30px is determined by a; the outermost layer is <ul id = "nav"> the width of 100%, and the height of 30px is determined by li.
