Extended knowledge:
DIV tags are called segmentation tags. The function is to set the placement position of words, paintings, tables, etc. When you put text, images, or anything else inside a DIV, it can be called a "DIV block", or a "DIV element" or a "CSS-layer", or simply a "layer". In Chinese we call it "level".
The DIV element is an element used to provide structure and background for block-level content in an HTML document. Everything between the start and end tags of the DIV is used to form the block, and the properties of the contained elements are controlled by the properties of the DIV tag, or by formatting the block using a stylesheet.
