Currently, it is not possible to upload templates. For a site to work in Yola, it has to be designed using one of the templates available from Yola. We have been working hard to expand Yola’s template selection and allow for more customizations with Yola’s current templates. Yola’s Responsive templates, in conjunction with Yola’s Style Designer, are Yola’s most flexible templates yet. You are able to control almost every element on your site. These templates are able to adapt to any screen size resolution!
If you go to Style > Designer, you will see a wealth of options available for you to tweak your site. Please have a look at Yola’s tutorial for helpful tips: Personalize your Style.
In addition, if you are a Yola Silver or Yola Gold customer, you have access to the Site CSS feature which allows you customize your site even further.
