html escape character newline

What should we pay attention to about HTML escape characters and line breaks?

In the HTML programming language, there are many special symbols that require escape characters to be displayed correctly, otherwise they will be regarded by the browser as HTML tags instead of text content. Commonly used HTML escape characters include: a8610c84b9b996446aafeab8e6428271 (greater than sign), & (& sign), " (double quote), ' (single quote), etc. These symbols are frequently used in HTML, especially These escape characters are essential when symbols without special meaning need to appear in the text.

Line breaks are also very important in the HTML programming language. Line break tags in HTML are divided into two categories: Block-level elements and inline elements. Among them, block-level elements include dc6dce4a544fdca2df29d5ac0ea9906b, e388a4556c0f65e1904146cc1a846bee, 4a249f0d628e2318394fd9b75b4636b1~4e9ee319e0fa4abc21ff286eeb145ecc, etc., while inline elements include 45a2772a6b6107b401db3c9b82c049c2, , etc. However, it should be noted that whitespace characters such as spaces, tabs, line feeds, and carriage returns in HTML will be automatically ignored when parsing HTML, and they will only be regarded as a space.

General In this case, we can use the
tag to wrap the line. The code is implemented as follows:

例：这是第一行<br>这是第二行

In this way, the effect displayed in the browser will be:

This is the first line
This is the second line

If we use multiple
tags in HTML, we can achieve the effect of multiple line breaks:

例：这是第一行<br><br><br>这是第四行

In this way, it will be displayed in the browser The effect will be:

This is the first line

This is the fourth line

If we want to use a simpler way to achieve the multi-line wrapping effect, we can use CSS The "white-space" attribute in the style sheet is used to process it. For example, the code is as follows:

<style>
p {
  white-space: pre-line;
}
</style>
<p>这是第一行
 
这是第二行
 
这是第三行</p>

In this way, the effect displayed in the browser will be:

This is the first line
This is the second line
This is the third line
