In order to present a beautiful and neat effect on the web page, various HTML codes are often used. Today, HTML has become one of the most commonly used languages on the Internet, but too much HTML code will cause web pages to load slowly and also make the code difficult to read and maintain. Therefore, to keep web pages light and manageable, we need to learn how to remove redundant and useless HTML code.
1. Remove whitespace and newline characters
In HTML code, there are often many whitespace and newline characters. These characters have no meaning in the web page effect, but will increase the file size. Reduce the loading speed of web pages. Therefore, when writing HTML code, you should try to avoid excessive whitespace and newline characters, and use tools to remove unnecessary whitespace and newline characters.
2. Use CSS styles
CSS styles can make the layout of the web page neater and reduce code duplication. By concentrating the definition of web page styles in a CSS file, the HTML code can be made more concise and easier to maintain. Therefore, when writing HTML code, you should use CSS styles as much as possible to replace repeated HTML code.
3. Merge JavaScript and CSS files
In web pages, JavaScript and CSS files are often used to improve the user experience. However, if multiple JavaScript and CSS files are used, it will cause the web page to load slower. To improve the loading speed of your web pages, you should reduce the number of JavaScript and CSS files as much as possible and try to merge them into a single file. This can be achieved by using compression tools and code merging tools.
4. Optimize pictures
Pictures play a very important role in web pages. Among them, most pictures have large file sizes, which may cause the loading speed of web pages to slow down. To reduce the impact of images on loading speed, you can use image optimization tools to reduce the file size of images and improve their quality.
In short, optimizing HTML code can make web pages more elegant, easier to maintain, and improve website speed and performance. Redundant and useless HTML code should be removed as much as possible, and CSS styles and optimization techniques for JavaScript and CSS files should be used as much as possible to improve the quality and user experience of the website.
