In order to understand the issue of floating, we must first understand the two states of html elements,
block elements, or inline elements.
1. Block elements have physical attributes and will occupy one line. Characteristics such as width and height can be set. Multiple block elements will be displayed in separate lines.
Representatives of block elements: div, p, etc.
2. Inline elements have no physical attributes and will not occupy a line. Multiple inline elements will be displayed side by side.
Representatives of inline elements: span , em, b, i, etc.
3. Sometimes the requirement is that you want certain elements to be displayed side by side and have settable physical properties. At this time, float is needed. Because HTML is a table structure, it is not responsible for the presentation level. At this time, a CSS attribute is needed to solve such a problem, and the float application was born.
The simple explanation is: it allows block elements to present the characteristics of inline elements to the outside and the characteristics of block elements to the inside.
Does this sentence mean the same as display:inline-block? In fact, it is like this. However, the compatibility of display:inline-block is not very good. There will be spacing under IE6, so float is used more often.
4. Float is not without its disadvantages. After float, it will have an impact on future sibling elements, so the css must be cleared before the sibling elements can be displayed normally.
