CSS Position Positioning essentials

I. Total of four positioning methods

1. static , this property default property, set before and after the left and right values do not affect the label position, fart with no.

2 relative, after using this property, you can show the coordinates in the original location for the origin of the left and right before and after the move. The original position is retained after moving, otherwise it will disturb the subsequent label positioning

3 Absolute, relative to the container before and after positioning, if the parent container label page does not include this property or the absolute property, relative to the entire HTML.

The parent container's CSS also joins position:relativ\ absolute\fix three properties, then the relative movement of this label moves around the container boundary to the left and right

The parent container does nothing or add staic, and the tag is all HTML-positioned.

4 Fixed in the screen guide position, does not change the position with the scroll bar change
