The absolute positioning and relative positioning of CSS style sheet of

css| style sheet positioning properties will be the key to the door of happiness for Web bugs:

Absolute positioning

H4 {position:absolute; left:100px; top:43px}

This CSS rule allows the browser to set the starting position exactly 100 pixels to the left of the browser, 43 pixels from its top, and see how the code works.

Note that the only set here is the left and the top, which means that the text will go from left to right, from top to bottom, to the Browse window.

The left and top properties are intuitive, and the left setting is the distance from the left side of the browser window, and the top set to the top of the browser window.

When you set these distances, you can use the various degrees of units or proportions you have learned. When using proportional values, the proportional value is relative to the parent element's dimensions.

Relative positioning

Absolute positioning allows you to accurately position the elements in a separate location on the page, regardless of the positioning settings for other elements of the page. Relative positioning refers to the position of the element you are positioned in relation to the location assigned in the file. Cases:

I {position:relative; left:40px; top:10px}

Please click to see how the code works

The key to relative positioning is that the position of the element is positioned relative to where it should normally be located. If you stop using relative positioning, the display position of the text will return to normal. Example.

Use relative positioning to be careful, otherwise it is easy to make the page very messy.

In addition to relative positioning and absolute positioning, you can also use static (static) parameter values. It is used in the same way as the normal HTML positioning method, and cannot attach special positioning settings.
