This is where many web developers tend to disagree. We can never seem to settle on a good code editor, ever. I’m going to leave you with a few of my favorites and some that I hate.
First off, I live and die by Macromedia Dreamweaver 8 Win/Mac. As a matter of fact, I also use Macromedia Fireworks 8 heavily for my web site designs. I just think that they have done a good job and incorporating HTML and CSS together. Especially with version 8.0. But then again, you get what you pay for because it’s going to set you back quite a pretty penny ($399). But it was a good investment for me.
On the other hand we have the Frontpage junkies. I haven’t really looked at Frontpage much since early 2000. I’ve opened up the version that comes with Office XP, but I was not impressed. What I do remember is that back in the day it was horrible. Frontpage used to dump a bunch of Microsoft specific “tags” into the code that it just served to bulk up the final output. There is the small advance of using Frontpage Extensions, which enable things like site counters and other things (sorry, I really haven’t been looking into it), but the problem lies in the fact that Frontpage extensions on servers usually cost more and they are very limited, and simply I haven’t heard anything about Frontpage lately, so I’m staying away from it.
For PHP editing I use a simply text editor called emEditor. One nice feature is tabbed editing. It also has syntax highlighting. Since I don’t write or compose very large PHP scripts, this is more than adequate for me.
When I’m at work and on Linux (Fedora) I stick to KDevelop. Most likely, I would be doing some C programming anyways, so it is just convenient since it is already opened to just drag and drop scripts and HTML files in there. I don’t, however, do any heavy HTML design on Linux though. I haven’t found tools suitable for such yet. There is something called NVU, but it just doesn’t do enough for me to design a site from scratch using this.
