Division in HTML refers to the use of division operators to perform mathematical calculations in HTML code. HTML is a markup language used to describe the structure and content of web pages. Although HTML is not a programming language per se, it provides some simple calculation functions, including addition, subtraction, multiplication, division, and modular operations.
Performing division operations in HTML requires the use of the division operator "/" to represent the division operation. This operator can be used in any attribute that can use numeric values, such as page styles, element attributes, and JavaScript code.
For example, the division operator can be used in a CSS style to calculate the width of a page element:
<style> #box { width: 50% / 2; } </style> <div id="box">这是一个文字框。</div>
The above code sets the width of the DIV element to 25% of the page width. This is because 50% divided by 2 is 25%.
Another example is using the division operator to perform mathematical calculations in JavaScript code:
<script> var num1 = 10; var num2 = 2; var result = num1 / num2; document.write(result); </script>
The above code divides the variable num1 by the variable num2 and stores the result in the variable result. Then, use the document.write() method to output the results to the page. The output result is 5, which means that the result of dividing 10 by 2 is 5.
The division operation is widely used in HTML and can be used in various scenarios. For example, when calculating data in a table, you can use the division operator to calculate the average, sum, or percentage of each cell.
In addition, HTML also provides some other mathematical operators, such as addition (), subtraction (-), multiplication (*) and modular operation (%). These operators can be used in various attributes of HTML to help developers perform more complex calculation operations.
In short, the division operator in HTML is a very convenient tool that can help developers perform simple mathematical calculations in web pages. The division operator can be applied to various HTML attributes and JavaScript code, providing developers with more flexibility and creativity.

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),
