Optimize HTML to Boost Web Performance
Following are some best practices for optimizing and improving the performance of HTML code:
Use semantic HTML
Semantic HTML elements are used to give meaning and structure to the content of a web page. Using semantic HTML makes it easier for search engines to understand the content of a page, resulting in better search engine optimization (SEO). Semantic HTML elements include <header> , <nav> , <main> , <section> , <article> , <aside> and <footer>.
Minimize HTML code
Minimizing HTML code involves removing any unnecessary white space, comments, and unused code. This reduces the size of HTML files and improves website performance. HTML compression tools like HTMLMinifier can be used to compress HTML code.
Use CSS instead of inline styles
Inline styles are styles applied directly to HTML elements using the style attribute. Using CSS instead of inline styles separates the presentation of a web page from its content. This improves the maintainability and readability of HTML code.
Use external CSS files
External CSS files are files that contain CSS code and are linked to from HTML files. Using external CSS files reduces the size of HTML files and improves website performance.
Use asynchronous loading for scripts
Scripts can significantly slow down the loading of web pages. Using the async or defer attribute to load scripts asynchronously allows the browser to continue loading the page while the script is being downloaded and executed.
Optimizing images involves reducing the size of image files without reducing their quality. This reduces the file size of HTML files, resulting in faster loading web pages. Image optimization tools like TinyPNG or JPEGmini can be used to compress images. The srcset attribute can also be used to serve different-sized images based on the device's resolution.
Following these best practices can help optimize and improve the performance of HTML code, resulting in faster loading web pages and better user experiences.
