In addition to our last blog post about the HTML5 template and system markup we now talk about our new CSS framework. We will explain how it works and how you use it.
The CSS Framework
So what is a CSS framework? A CSS framework is a rich tool set of useful CSS classes to style HTML markup. It provides cross-browser support and enables you to build robust and future-proof websites. For Warp6 we created our own CSS tool set. It is a collection of best practices we learned in the last 5+ years of theme development. Of course we also kept track with the major CSS and grid frameworks which popped up in the last years and what we can learn from them to improve our code.
One of our major goals was to keep the CSS as modular as possible. Sometimes you just need a specific part of the tool set and you don't want to load unnecessary CSS files. That's why we keep them in separated files and each one has it's own file specific purpose like the layout, menus, etc. These framework CSS files are located in the Warp6 CSS folder. A theme itself has its own CSS files and you have full control which parts of the framework CSS you want to load and which not.
The complete framework CSS uses 12 different files which are well documented with comments. Each file is stripped down to the essential, no duplicate code and we utilized the full power of CSS 2.1 selectors. The build-in compression feature of Warp6 automatically combines the style sheets into one file, minifies the code, compresses the final CSS file on-the-fly using the GZIP data stream compression and caches it. No need to worry about loading times. We promise that Warp6 is fast - very fast!
Now a closer look at the CSS framework followed by a short description of the different framework CSS files.
No Overflow Hidden!
We didn't use any
overflow:hidden in the whole CSS, not even for clearing. This is because
overflow:hidden has a major drawback. It will clip elements that you're trying to position outside of it. But even worse is that it also clips new CSS3 properties like box shadow. By not using any
overflow:hidden you have more possibilities to use CSS3 properties and position elements where you want.
The Grid System
Another really important part of our CSS framework is the grid system. We don't want to dive that deep into the different types of grid systems. Just a short round up what we have done and why we feel it is a good approach.
Most grid systems like 960 Grid System, Blueprint or 1KB CSS Grid use a fixed template width and a pixel based grid unit. It is possible to integrate one of these systems into a theme framework but if you want to keep flexibility it feels like making things a bit too complex. This doesn't mean using one of these grid systems is a bad idea. So we come up with a own grid solution which is simple and flexible.
Here is a brief description of the different CSS files provided by the framework.
Yes, that's right! We have no Reset CSS. We take a different approach: To avoid redundant code we set new default values instead of baseline defaults and re-resetting them later.
The layout style sheet provides a fluid grid and helper classes to create any layout and some layout defaults.
The menus style sheet defines base styles for various menus. Currently we support our famous Mega Drop-Down Menu, the Accordion Menu and the Line Menu for the top and footer positions.
The modules style sheet defines general module defaults, headings, badges and icons.
The tools style sheet provides a useful set of CSS classes to style your content. For example this includes read more buttons, different list, table and form styles, info boxes and more.
The system style sheet defines a base style for the WordPress, Joomla 1.5 and 1.6 system HTML markup.
The RTL style sheet is used for right-to-left language localizations. We are proud that Warp6 has full RTL support.
The print style sheet which is only used when printing.
The mobile style sheet which styles the template for mobile phones.
ie.css, ie7.css, ie8.css
We provide different IE style sheets which are only loaded by the specific Internet Explorer version.
The style style sheet defines the main look like colors and backgrounds which may change for different theme styles. Having all style related CSS in one place makes creating style variations very easy.
The custom style sheet should be used to style your content. It is blank by default.
Warp6 provides a flexible CSS framework which is divided into different files and for each purpose. A Warp6 theme itself has its own CSS and you have full control which part of the framework CSS you want to load and which not. For example if you want to use the 960 Grid System instead of the provided one you are free to do so. The provided grid system is very flexible, the smallest in size and didn't make use of any
overflow: hidden. We love it!
