6.1-6.5 about HTML

Web pages are generally composed of two elements, one is an inline element,

That is, inline display, plus width and height have no effect.
One is the chunk element, which can be added with the corresponding width and height,

Usually used in the layout of the Web page, the most commonly used is the <div> tag.

Display:block to convert an inline element to a chunk element
Display:inline: To convert a chunk element into an inline element

For example:
<span></span> is an inline tag, and if you want to use it as a <div></div> tag,

At this time display:block, it can be used! (Note that the use of any label is best followed by Web standards)
<ul><li></li></ul> is a block-level element, and if you want the list to appear on one line,

In this case, the <li> tag can be set display:inline;
