CSS block-level tags, inline tags, and inline block tag conversion (2)-CSS Tutorial-php.cn

HTMLClassification of tags

When talking about tag classification, as beginners, when we first use tags, we will find that some attributes are on some tags Does not work, such as width, height, horizontal centering, etc. In fact, the use of this attribute only works when used on block-level tags. Personally, I think this is something that beginners can easily overlook, so I wrote it down!

First of all, we can divide theHTMLtags into block-level tags, in-line tags, and in-line block tags according to the differentdisplays; now we will introduce them respectively. .

Block-level tags

## Features:is on one line, It takes effect for the settable attribute values of height, width, line height, and top and bottom margins; if no width is given, the block-level element defaults to the width of the browser, which is100%width;

Typical block-level tags are:

, h series,

Inline tag

can be multiple Each label exists in one row. You cannot directly set the height, width, row height, and top and bottom margins of the in-line label. The width and height are completely dependent on the content!Typical inline tags are:,,,,,,,

Then some students will think, can’t I control the width and height of span or font? Yes, let’s put aside floating and positioning this time, and let’s convert them to each other through the display attribute:

1. Convert block-level tags to inline tags: display: inline;

2. Convert inline tags to block-level tags: display:block;

3. Convert to inline block tags: display:inline-block;

As long as you use the display attribute for the corresponding label and take the corresponding value, you can convert the display modes to each other.

Already mentioned above Let me emphasize the difference between inline block-level tags and block-level tags: both block-level tags and in-line block-level tags can be set in length and width, but block-level tags need to be set after you set them

It is automatically wrapped. You cannot put anything else on this line. Inline block-level tags can place multiple inline tags on the same line. I have a case to explain specifically.
