CSS block-level elements and row-level elements (reprinted)

1. Block elements generally start on a new line. It can accommodate inline elements and other block elements. A common block element is the paragraph tag 'P". The "form" block element is special. It can only be used to accommodate other block elements. .
3. Without the effect of css, the block elements will be sequentially arranged one line at a time. With CSS, we can change the default layout mode of this HTML and place the block elements where you want. Instead of stupidly starting a new line every time. It should be pointed out that the table tag is also a type of block element. Table based layout and css based layout look at these two layouts from the perspective of ordinary users (excluding visually impaired people, blind people, etc.), except for page loading speed. Except for the difference, there is no other difference. But if an ordinary user inadvertently clicks the View page source code button, the difference between the two will be very large. The CSS layout page source code designed based on good reconstruction concepts can at least allow ordinary users without web development experience to quickly understand the content. From this perspective, css layout code should have a better aesthetic experience.
5. You can think of the block container element div as boxes, or if you have played with clipping, it will be easier to understand. We first cut out the necessary articles from various newspapers and magazines. Each piece of cut content is a block. Then we glued these pieces of paper onto a new piece of blank paper according to our layout intention. This will form your own unique abstract. As an extension of the technology, web layout design follows the same pattern. . 
7. Inline elements are generally based on basic elements at the semantic level. Inline elements can only accommodate text or other inline elements. The common inline element is "a".
9. Block element and inline element are both concepts in the HTML specification. The basic difference between block elements and inline elements is that block elements generally start on a new line. When CSS control is added, this attribute difference between block elements and inline elements no longer becomes a difference. For example, we can add an attribute such as display:block to the inline element cite, so that it also has the attribute of starting from a new line every time.
11. The basic concept of a variable element is that it needs to determine whether the element is a block element or an inline element based on the context. Variable elements still belong to the above two element categories. Once the context determines its category, it must follow the rules of block elements or inline elements. See full text for rough element classification.
13. Regarding the Chinese name of inline element, there are many kinds of inline elements, inline elements, inline elements, and inline elements. Basically there is no unified translation, just call it whatever you want. In addition, when talking about inline elements, we will think of a display attribute called display:inline; this attribute can fix the famous IE double floating border problem.
