styles
This is RapidWeaver's Page Inspector, showing adjustments that can be made to a typical template, or theme as it's known in the RapidWeaver community. Not as much control as I was used to, but it wasn't half bad. Then I got to thinking—how many layouts can you use to design Web pages anyway? There's a limit to the combinations of sidebar, header, and main content, and after looking at the themes that ship with RapidWeaver, I could see all the variations I was likely to need there. In fact, looking back on the sites I've designed in the past, there was nothing there that wasn't the same layout as at least one RapidWeaver theme. Then I thought: 'But what if the client wants the navbar a smidgen narrower, or the header not quite so deep?' Am I going to tell him 'Sorry, I'm using a template, and I can't alter it'? I couldn't see myself doing that. So I joined the RapidWeaver forum and started asking questions, and got some interesting answers, really fast. Great forum. Turns out that you can go way beyond the adjustments shown above, by entering custom CSS in a box in the Page Inspector.

Here's the Page Inspector showing the box you enter it in. Trouble was, I didn't know any. But something strange happened—when it turned out that I HAD to learn at least a bit of CSS, I found I was enjoying it. All the years I'd used other applications, I'd never felt that I would ever be able to learn to code; RapidWeaver actually made it fun!

Here's how it came about: I'd decided, against all common sense, to do an actual paying job using RapidWeaver. I wasn't going to use any of the header images in the theme and in any case, the client wanted her own. Thing was, there were fourteen pages, and the theme I was using could only give me eight. So I wrote to the RapidWeaver forum to ask what I should do. I'd been thinking that I could always duplicate the theme and set up different header pictures in each, although that sounded a bit clunky. Sioni, a resident genius, came to my rescue within the hour, and explained how to do it via CSS, without having to use any of the included header 'slots' in the theme. There's a tutorial later in the site where I've explained how to do what I learned.
I was surprised how, after saying I'd never get involved in any sort of code, it was so easy to pick up. It's really the syntax that matters; you can look up the actual values at dozens of places on the net (try here, here or here) or use this great Dashboard Widget, but the important bit is the way you write it in. I'd say to anyone still thinking they'll never be able to do it: try, it's not that difficult. Not that I'm even close to being an expert yet, but I can do enough to take away the 'it's a template' worry.
