Three forms of the basic layout model and layer model of Css:3

The CSS contains 3 basic layout models:

In English: Flow, Layer, and Float.
In a Web page, elements have three layout models:
1. Flow model
2. Floating model (float)
3. Layers Model (layer)

The flow layout model has 2 more typical features:

1th, the block element extends vertically from top to bottom in the containing element , because, by default, the width of the block element is 100%. In fact, a block element occupies a position in the form of a row. As in the right-hand code editor, the three-block scholar-label (div,h1,p) width is displayed as 100%.

2nd, in the flow model, the inline elements are displayed horizontally from left to right within the containing element in which they are located. (inline elements are not like blocky elements so overbearing exclusive line)

There are three forms of the layer model:

1. Absolute Positioning (Position:absolute)

2. relative positioning (position:relative)

3, fixed positioning (position:fixed)
