Here's how to change your style/template:

1. Click on the Style tab in the Sitebuilder. 
2. You can scroll through all the styles, or separate them into free and Premium Styles.
3. Many of the styles are customizable! Hover over the thumbnail to view the styles features.
4. When you've decided on the style you would like to use, click on it. It will be applied to your site. 
5. If you're happy with the style, simply continue editing your site.  

If you're a Yola Free user and you've selected a Premium Style, you can try out the style on your site for free before making your purchase and you will be prompted to upgrade to Yola Silver the next time you publish your site.
