How to Optimize Your Theme for Maximum Speed
One of the easiest ways to improve the speed of a WordPress website is theme optimization. In the following paragraphs you will learn how to decrease the size of your theme package and decrease loading time.
Get rid of images
CSS 3 allows you to create visually appealing designs without the use of images. For instance you can create the shadow effect, rounded corners and beveled lines with a few extra lines of code. Unfortunately older browsers do not support CSS 3. However you can easily work around this problem by creating separate style sheets for older browsers like IE 6. An image-less web page is much faster as compared to the one with images.
If your design is very complex and using images is necessary then you should compress them before use. This will bring down the overall size of your page and you will see a considerable improvement in speed.
Compress the code
Spacing is important for readability but it increases the size of your pages. Therefore it might be a good idea to compress all your code before uploading it to your WordPress site. There are many online tools that can help you do that quickly and safely. But you shouldn’t use this tactic if you are creating a theme for a client or a marketplace like Theme Forest. In such cases ease-of-use must be your first priority.
Don’t overuse third-party scripts
Third-party scripts like Cufon and Tim Thumb are great but they can slow down your website. Therefore you should only use such scripts when there is no other alternative available. For dynamic thumbnails you can use WordPress’ own thumbnail functions. Similarly you can use Google Fonts instead of Cufon.
