CSS display: inline and float: left the difference between CSS display refers to the display status, inline indicates inline, characteristic is closely related to the previous inline element, usually the default inline element has span, a, em, strong, etc. Float indicates floating, float: left, which is the floating form of block-level elements and two States of different forms. First, we need to clarify the correct meaning of CSS display: inline; and float: Left. CSS display: inline; (Inline) text display in the CSS authoritative guide: any visible element that is not a block-level element is an inline element. Its performance is in the form of "Row layout", where "Row layout" means that its performance is always displayed in rows. For example, when we set an inline element border-bottom: 1 pxsolid #000;, it is represented by repeating each line, with a black fine line under each line. If it is a block-level element, the displayed black line will only appear below the block. Of course, this does not look like CSS.
The difference between display: inline; and float: Left; but when we understand the features of float: Left;, we know exactly what is going on. Float: Left; (left floating) It makes the specified element out of the normal document flow and produces a special layout feature. In addition, float must be applied to block-level elements, that is, float is not applied to inline labels. Or in other words, when float is applied, this element will be specified as a block-level element. It is clear that the inline (CSS display: inline;) element cannot be set in width or height, because inline is a row layout and its feature is to layout in a row, therefore, the width and height cannot be set.
