Minimise the Use of HTML Tags

When you create your HTML structureIf you're using tags, it's essential to minimise the use of unnecessary tags. Every tag you add means more weight for the browser, which can slow down page loading. Use appropriate semantic tags and avoid excessive div containers.

Optimise your CSS Styles

As for CSS, it is advisable to avoid inline styles and opt for external stylesheets instead. Be sure to combine and minimise your CSS files to reduce server requests. Also, use efficient selectors and avoid redundant or unused rules.

Asynchronous Resource Loading

To speed up the loading of your site, consider implementing asynchronous loading of resources, such as images and scripts. This allows certain elements to load in the background, without interfering with the initial rendering of the page. Use attributes such as "async" and "defer" to control the loading order.

File Compression

To further optimise performance, compress your HTML files, CSS and JavaScript. Compression reduces the size of files, which translates into faster loading times. You can use tools such as Gzip to compress your files effectively.

Content Caching

Implement Media Queries
