How to leave two spaces in a paragraph: 1. Use the text-indent attribute of CSS; 2. Use the padding-left attribute of CSS; 3. Use non-breaking spaces or full-width spaces; 4. Use "pre" label or white-space attribute.
In HTML, the function of emptying two spaces in the first line of a paragraph (commonly known as indentation) is not like that in some text processing software. So direct. HTML itself does not contain tags or attributes that directly control text indentation. However, we can use CSS (Cascading Style Sheets) to achieve this requirement. The following are some common methods to achieve the effect of two spaces in the first line of an HTML paragraph:
1. Use the text-indent attribute of CSS
The text-indent attribute uses Sets the indentation of the first line of text. It accepts various units such as pixels (px), percentages (%), em, etc. If you want the first line of a paragraph to be two spaces empty, use the em unit because it is relative to the font size of the current element. Usually, the width of a Chinese character is about 1em, so setting text-indent: 2em; can achieve the effect of two spaces.
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>段落首行空两格</title>
<style>
p {
text-indent: 2em; /* 首行缩进两个字符宽度 */
}
</style>
</head>
<body>
<p>这是一个段落，首行会空出两个字符的宽度。</p>
</body>
</html>2. Use the padding-left attribute of CSS
Although padding-left is not specifically used to achieve the first line indentation , but a similar effect can be achieved by adding left padding to the paragraph. However, this method is not a true first line indentation, but extra space on the left side of the entire paragraph, which may affect the layout of the paragraph and other elements.
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>段落首行空两格</title>
<style>
p {
padding-left: 2em; /* 段落左侧添加两个字符宽度的内边距 */
}
</style>
</head>
<body>
<p>这是一个段落，整个左侧会有额外的空间，看起来像是首行缩进了。</p>
</body>
</html>3. Use non-line-breaking spaces or full-width spaces
Insert multiple non-line-breaking spaces directly into the HTML content ( ) or full-width spaces can also achieve the effect of visual indentation. However, this method does not control indentation through CSS styles, but directly adds spaces to the text content, so it is not flexible enough and is not conducive to maintenance and style uniformity.
Example:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>段落首行空两格</title> </head> <body> <p> 这是一个段落，通过在内容中添加非断行空格实现首行缩进。</p> </body> </html>
4. Use tag or white-space attribute
tag is used to display pre-format ified text, which preserves spaces and newlines. However, this is usually used for code presentation and does not apply to ordinary paragraph text. In addition, you can use the white-space property of CSS to control how whitespace characters in the text are processed, but this is not specifically used to achieve first line indentation. <p>Note: </p><p>When using text-indent, make sure your font size is appropriate, because the indent is calculated based on the font size of the current element. </p><p>Different browsers and rendering engines may handle text-indent slightly differently, especially when dealing with complex fonts and typography. </p><p>When using padding-left to simulate first line indentation, be aware that it affects the left margin of the entire paragraph, not just the first line. </p><p>The method of directly adding spaces to the text content is not flexible enough and is not convenient for unified management and maintenance of styles. </p><p>In practical applications, the appropriate method should be selected based on specific needs and context to achieve the effect of two spaces in the first line of a paragraph. </p><p>In general, using the text-indent property of CSS is the most common and recommended way to achieve two spaces in the first line of an HTML paragraph. It provides a flexible control method and is separated from the semantic structure of HTML, which facilitates unified management and maintenance of styles. </p>

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
