Extended knowledge:

(1) vw, vh, vmin, and vmax are window units and relative units. It is not relative to the parent node or the root node of the page. It is determined by the size of the viewport. The unit is 1, which means something like 1%.

The viewport is the area where your browser actually displays content—in other words, your web browser without toolbars and buttons.

(2) The specific description is as follows:

• vw: the percentage of the window width (1vw represents the width of the window as 1%)

• vh: The percentage of the window height

• vmin: The smaller of the current vw and vh

• vmax: The current vw and vh The larger value in vh

The difference between vw, vh and % percentage

(1) % is the size relative to the parent element The set ratios, vw and vh, are determined by the window size.

(2) The advantage of vw and vh is that they can directly obtain the height. However, using % cannot correctly obtain the height of the visible area without setting the body height, so this is a good advantage.
