We're ready to start digging into really building our theme. My favorite way to do that is to start with a blank theme. So again we're looking at the 2010 theme that came with WordPress. It's a nice-looking theme, but we've already created our Photoshop file. We've created our CSS and HTML template. We know what our site is going to look like and it's not like this. So we're going to actually remove this theme entirely and replace it with a blank theme. Blank themes are great, because it's not going to be us wrestling against this existing theme.
It's going to be starting with absolute and complete scratch and you'll see what I mean in a minute. If you don't have access to the exercise files, I've included the blank theme as the free exercise file that you can download from the course page. So this is the WordPress theme. Now how do you install a WordPress theme? Where do WordPress themes go? Well, these are the files in the Applications folder in the MAMP folder in the htdocs folder. Remember that's where we installed WordPress. That's where all the files that power WordPress are. I'm going to drag this htdocs folder into our sidebar over here so we can have easy access to it moving forward.
There is a folder in here called wp- content and within that there's a plug-ins folder, a themes folder, an upgrade folder. Within that themes folder, our folders for each of the themes that are installed and ready to go, ready to be switched between in the WordPress lane. There's only one folder in there. That's the twentyten theme. So, from our WordPress site we're going to go to the Dashboard by going to wp-admin and click on the Appearance button over here and that'll show us that current theme that's activated on this site.
Notice there's only one in here and that's exactly what we're seeing here. There's only one theme available. Well, here's our BLANK_Theme. I'm going to hold the Option key and drag it over to the themes folder. That's going to copy it over there. Now there're two themes available in our themes folder and if we reload the page over here in our admin area, it's going to now show us that the currently active theme is still 2010, but there's an additional theme available and it's here. It's not the active theme, but there are some options. We can activate it, preview it, and delete it.
Let me click Preview, so you can see what that looks like. It basically opens what our site would look like in an iframe style popup. So, hopefully you weren't freaking like, whoa, what's that? That looks broken. It looks weird. It looks completely unstyled, but that's what a blank theme is. It's not broken that's what we're looking for. We're looking to start from absolute scratch with this theme rather than fight against the existing theme. So from here we're able to activate it, and that's fine. It's just this preview is nice if you're working on a live site. You can see what a new theme looks like and even click it out and interact with it without activating it.
So you don't have to worry about people seeing that where you're really just playing around. So of I Command+Click the title of our site here, we can open up the front of our site in a new tab, and that's what our site is looking like. Completely blank, it's a great starting point for our theme. A quick little thing that I want to touch on is if we click to open all the theme files, so here's all the files that are this theme, there's one file in here. It's actually required file in all themes. It's the style.css file.
I'm going to click-and-drag it onto TextMate and open it up in the text editor we've been working with. Notice, there's a bunch of comments at the top of this CSS file. This is where we can brand our theme and say that this is the Widget Corp Theme and it's a theme for widgetcorp and we can give it a description and the author and say what version it is and stuff like that and hit Save. It doesn't really show up anywhere except for here in the Appearance area of WordPress. So if I reload then, it'll say this is really now the Widget Corp theme, number 1, version 1, by me, and with the description that we gave it and all that.
Notice there's also a thumbnail for it that says BLANK THEME. That's just what, this screenshot.png. I can double-click to open to open it. It'll open and preview and it's just this graphic that shows kind of an example. So if we open the twentyten, it also has that file, but it's exactly what you're seeing down here. It's just a preview of what your theme looks like. So if you wanted to change it, put some widgets in here, make it real obvious that this is the Widget Corp Theme. That's how you would do that. Starting fresh is a great way to start with a new theme, especially like us since we already have that HTML and CSS going, to not have to fight against an existing theme.
So now we have a great foundation for digging in with some real code.
