Block elements are generally the container elements of other elements. block elements generally start from a new line and can accommodate inline elements and other block elements, the common block element is the section tag 'p. The "form" block element is special. It can only accommodate other block elements.

If no css function is available, the block elements are arranged in the order of each row. With css, we can change the default layout of html and place block elements in the desired position. Instead of just starting another line. It should be noted that table labels are also a type of block elements. table based layout and css based layout are from average users (excluding persons with visual impairment and blind people) the two la s have no difference except the page loading speed. However, if a common user inadvertently clicks the page source code button, the difference between the two is very large. The css layout page source code, designed based on a good refactoring concept, can at least allow common users without web development experience to quickly understand the content. From this perspective, css layout code should have a better aesthetic experience.

You can think of the block container element div as a box, or it is easier to understand if you have played the clipboard. First, we cut down the necessary articles from various newspapers and magazines. Each piece of cut is a block. Then we pasted the paper block to a blank new paper with glue based on our typographical intent. This forms your own unique digest Express.

Both block element and inline element are concepts in the html specification. The basic difference between block elements and inline elements is that block elements generally start from a new line.

For example, we can add the inline element cite to the display: block attribute so that it also has attributes starting from the new line each time.

The basic concept of a variable element is to determine whether the element is a block element or an inline element based on the context relationship. The variable element still belongs to the above two element categories. Once the context relation determines its category, it must follow the block element or Inline element rule restrictions. For rough element classification, see the full text.

Ps: for the Chinese name of inline elements, there are multiple inline elements, embedded elements, in-row elements, and straight-forward elements. Basically, there is no unified translation. What do you call love. When we mention inline elements, we will think of a display attribute: display: inline; which can fix the famous IE Double Floating boundary.
