I've uploaded the themes that people requested, by converting wordpress themes to dokuwiki themes. I would have done this months earlier (or maybe 2 years earlier), but I was sick and recovering from sickness. Now to work on more themes.
Parabola will be worked on later as I had a problem with the dokuwiki css parser, which I'm fixing.
The only theme I didn't do on request, is the Simpleste theme, as it's not really a theme. It's more like a CSS framework. and a very lackluster one at that.
Here is what the Simpliste theme looks like. All changing the colour scheme does is change the red colour in the image to a different colour. So when thinking about it, it's not really a theme, with even much less design elements than css layout frameworks like Bootstrap.
Now, the natural question is how to do it...
I remember the days of CSS 2, everything was simple and a web developer could be assured that they know virtually everything about CSS. Programs like Host M Simple CSS and Blumentals Rapid CSS gave a person everything they needed to know in a slick interface. Those days are over. Then HTML 5 came out with the introduction of CSS 3. Years later WHATWG decided to stop using version numbers for HTML 5 and change it to a "living standard" so there is always new features with no version numbers and no milestones to be reached by a certain date. So there's no real reference point to look back to, or estimated delivery date for any of the new HTML and CSS features, and new features keep being added every year.
For me anyway there are 4 things to consider when making a design with CSS. Laying out the grid, rows and columns keeping everything aligned properly; the elements that go inside it, media queries, and having knowledge of the different selectors and attributes.
