In-depth understanding of float, inline-block, and floatinline-block
This article mainly introduces the introduction of float and inline-block, and analyzes the compatibility and influence on the parent element. It is recommended for reference by our partners.

ObjectiveTo explore block before you talk about my understanding of block, I interpret it as: a function pointer, an anonymous function, or a closure that captures variables inside its function . Note that the red part is about the essence of it. Hope to see me this article of the people can tell me the steps to do, do it is relatively simple, this will have a better effect, of course, if only read the ar

It is a separate rendering area that only block-level box participates in, which specifies how the internal block-level box is laid out and irrelevant to the outside of the area. So, how do you create a block-level formatting context a

The block element will have a single row, and multiple block elements will have their own new row. By default, the block element width automatically fills the width of its parent element.
The block element can set the Width,height property.
