Performance Optimization

There are quite a few ways to improve your HTML code to optimize the performance of your website. This performance improvement can come in the way of improved time to load your page, improved search engine optimization, and improved user experience.

Lazy Loading

Lazy load is an HTML attribute that can be applied to images and iframes in HTML: <img loading="lazy" src="image.png" alt="">. When one of those elements has the loading="lazy" attribute, it will not be loaded on the first render of the webpage unless it is visible on that first render. For example, if an image was only displayed after a button was pressed by the user, it would make sense for that image to be lazy loaded to make the first render of the webpage faster. Utilizing lazy loading can be very useful to optimize the performance of a webpage with many different menus with lots of images.

Reduce the Footprint of your HTML

Removing unnecessary whitespace and comments in your HTML is a common way to improve the performance of a webpage. Another way to clean up your HTML while also providing improved performance is to avoid using nested elements. For example, using a nested table to layout your page. On a similar note, creating separate files for HTML, CSS, and scripts can also improve the performance of a webpage. If you are using an external domain to import CSS, scripts, or other resources like images, limiting the amount of external hosts can make your website much quicker to load for a first-time user. Every different hostname requires a different DNS lookup by the user, which can add up to a noticeably slower experience, especially on less powerful devices like cell phones. Utilizing image sprites can also improve performance. An image sprite is essentially a collage of many images you are using on your website, edited together into a single file which you use HTML and CSS to crop down into many individual images to use on your website. Allowing the user to load a single image file instead of a collection of many different ones can improve load times.

Cross Browser Testing

Cross browser testing is an in-depth way of testing your web pages. By checking how your page appears on many different browsers, operating systems, and platforms, you can ensure a high quality and consistent experience for all users. There are many tools available online to assist with this process, with a common one being BrowserStack.
