Differences between inline and block:
A webpage is usually composed of two elements. One is an inline element, that is, the display in the row. Adding width and height does not work.
One is block elements, which can be added with the corresponding width and height. usually used in the webpage layout, the most commonly used is the <div> label. Display: block, which means converting inline elements into block elements display: inline, which means converting block elements into inline elements, for example: <span> </span> is an inline label. If you want to use it as a label such as <div> </div>, you can use display: block! [Note that the use of any tag best follows the WEB standard] <ul> <li> </ul> is a block-level element, if you want to display the list in one row, you can set display: inline for the <li> label;
