The templates created by RockSolid Themes are awesome: Clean design, clear structure, extremely high flexibility and tight integration into Contao. That makes customization super simple without mental acrobatics and trickery. I can only recommend everyone to have a look at the free template "Open Sauce" an to install it.

Theme Assistant - FAQ

How does the Theme Assistant work?

The Theme Assistant lets you control the design of your website without code and generates standard compliant CSS3. Even complex shadows, buttons and gradients can be changed and are kept in harmony. Without database requests and bloat or performance loss and free from dependencies.

Who can benefit?

Do-it-yourselfer as well as professionals! Change the colors, logo und make common customization effortlessly. The resulting CSS is flawless – you can use it right away or make changes to it, if you want to.

What can I customize?

Amongst other things: Colors (links, buttons, boxes), backgrounds (colors, images), Logo, Fonts, the width of the page and images, social media icons...

Expert: Does the Theme Assistant lead to bloated CSS like other themes that offer settings?

No, your settings are translated into clean CSS and are directly saved into the stylesheet – no additional requests. The generated output looks like the code you would have written yourself. Not a single line of overhead.

You can edit the resulting code easily, if you want to make changes to single elements. Uninstall the Theme Assistant without a trace at any time. This way you can make common changes in minutes and individualize every single detail afterwards.

Important: The color sets don't add overhead either. Unlike the solutions of other premium theme vendors the Theme Assistant stores the color variant separately and only inserts them into the stylesheet if you choose to. Take a look at the theme detail page to see which color sets come with your favorite theme.

Expert: Does the Theme Assistant slow down my page like the common options panels?

No, the resulting styles are, just like handwritten CSS, written directly into the stylesheet and thus completely cached, minified and gzipped.
