The speed of the mobile website is dragging down the user experience on my

I'm working on creating a prototype for the mobile version of a website, utilizing only jQuery and Foundation 4 with no dynamic elements. Unfortunately, when I view the site on an iPhone browser, it loads very slowly and is unresponsive to touch commands. I would greatly appreciate advice from more experienced individuals on how to improve the loading speed and responsiveness of the site on mobile devices.

All my images are optimized for web usage, so that shouldn't be causing any issues. Could the slow performance be due to the extensive length of my CSS stylesheet? I haven't mastered the art of combining and applying classes efficiently, leading to numerous IDs and separate classes - could this be impacting the speed of the site? Additionally, is the use of Foundation, jQuery, and Flexslider plugins contributing to the sluggishness? Should I consider removing any unnecessary files from their respective folders? Am I headed in the right direction, and what other steps can I take to enhance performance? Your assistance is greatly appreciated.

Answer №1

Improving the speed of my mobile app was a priority for me, especially when facing slow screen response times like you have.

Clean Up Unused Code

I found that removing unused code and files, including unnecessary CSS styles, greatly improved performance.

Consider Class and ID Usage

Instead of assigning a class or ID to every element in your app, consider using more efficient selector methods based on the DOM structure.

Evaluate Your CSS Styles

Avoid redundant CSS styles that do not contribute to the functionality of your app, such as applying both float: *; and display: inline-block; unnecessarily.

Optimize Your Scripts

Simplify your code by consolidating similar functions, utilizing premade functions, and seeking optimization tips from resources like this.

Refine jQuery Selectors

Make your jQuery selectors more specific to improve efficiency, particularly when targeting specific elements within a larger group.

Efficiently Store Information

If you repeatedly use calculated values in your app, store them as variables to reduce computational load and enhance performance.

Avoid Unnecessary Plugin Usage

If you only utilize a small portion of a plugin, consider alternatives or custom solutions to prevent loading unnecessary files that could impact performance negatively.

These strategies significantly enhanced the speed of my app, and I hope they prove beneficial for optimizing yours as well.

Feel free to provide corrections or additional insights if needed.
