Three, summary
-
What are the solutions to this problem?
float / absolute positioning / flexbox / table layout / grid layout; -
The advantages and disadvantages of each program?
1) Floating
Excellent: Simple,
Lack: Break away from the document flow and need to be combined with the BFC application.
Note: You need to write the floating block level first! ! !
2) Absolute positioning.
Excellent: Simple . Shortage : Break
away from the document flow and need to be combined with BFC applications. There are more codes.
3) Excellent flexbox
: Simple and fast, with good compatibility.
4) Table layout.
Excellent: Good compatibility . Shortage : The
height of each column will change at the same time. ; The table needs to be rendered first, and the page generation speed is delayed.
Note: The block level set to "display: table" needs to set width: 100%.
5)
Excellent grid layout : It can achieve complex operations with multiple rows and multiple columns, and has better compatibility. Okay, simplify the code -
Are there any compatible solutions?
flexbox, grid layout
*There are still many shortcomings in the code. We hope to put forward different opinions and communicate with each other. *
