I'm new to all this, and I'm currently designing a web site. Once it's online, how can I experiment with design and colors for better revenue rates (affiliates and AdSense)? I'm using GoLive, with templates I made, so some things can be easily updated, like text size and colors and stuff. But the basic layout can't be changed without going into each page and manually changing them. How do people with sites that have 100's of pages do this? Even now, I only have about 20-25 pages so far, but sometimes I get a good new idea, and have to go tweak the rest of the pages and it takes a looong time! Do you just have to suck it up and change dozens of pages when you want to try some little tweak, or do you just tweak a few pages, have a site that isn't completely consistent design-wise, and wait and see if it's worth it to change all the pages?
Alot of people use CSS when designing websites. This is a simple language that you can use in conjunction with your html. You make one file that contains all the site attributes e.g. font size, font colour, layout dimensions, so if you want to change something on your site you only have to change it once. I hope you have been testing your site in different browsers as this is usually one of the first things to bite a new web designers ass. You'll probably find that they look slightly different in different browsers.
Yeah, I use CSS for general font stuff, h1 tags and so on. I was thinking for design things that can't be easily changed, except one-by-one. How does a site with dozens or hundreds of pages do this? I guess the big ones just hire people to manually redo their pages, like if they want a site re-design?
Well, if the layout is controlled via css then you just change one .css file Bigger sites usually use somekind of cms and then they change only layout which effects the whole web. p.l.u.r.
