I've created a WordPress.com blog/site using the Triton Lite theme. There are a few things I'd like to change (eg, I'd rather not have to roll over the posted images for them to appear at their maximum brightness). To make these changes, I understand I have to self-host and modify the theme (eg, in Dreamweaver). To this end, I've learned some HTML and CSS, as well as Dreamweaver, and am in the process of learning more via Lynda.com's fantastic tutorials.
I assume the next step is to install WordPress on my laptop and establish some kind of connection with GoDaddy's servers (I registered the domain name with them; they also host), then edit (in Dreamweaver) the HTML and style sheet for the theme, and upload the new theme, with my content, to GoDaddy's servers.
For the life of me, though, I can't figure out how to do this. I started watching the WordPress Essential Training video on Lynda.com, and am struggling to get past the basics (the second tutorial: "Getting the necessary info from your host")--though the author's videos--like all the videos on Lynda.com--are usually very easy for me to follow. Part of my problem is that GoDaddy's interface (all bells and whistles) differs from the BlueHost interface the tutorials show, but of course there's also the fact that I'm ignorant and out of my depth. So I need to start from a lower rung than "Essential Training." Can anyone help?
