Of the many great reasons for using WordPress to create your web site or blog, one of the most important ones is that WordPress is an ever evolving platform. That means with every new version release you can expect to see either security and usability upgrades, or the addition of whole new features. In the case of the latest WordPress evolution—version 3.4, released for WordPress.com and WordPress for self-hosting—we see both regular security hole fixes and code patches, as well as some cool new features for site owners and developers. One feature in particular that is worth special mention is the new Theme Customizer.
Using the WordPress 3.4 Theme Customizer The major update of 3.4 is the introduction of the Theme Customizer. This new feature makes it possible for an administrator to change most theme-related elements of a WordPress site in a live environment and see how those changes look before publishing them to the live site. Previously these customization features were found under several different sections in the admin area, and to apply them you had to make one change at a time and then open the site in a different window to see the result. The Theme Customizer is a one-stop-shop for theme customization, and depending on what theme you are using, you’ll be able to change everything from the site title and description, to menus, what is displayed on the front page, background colors, header images, and more. Once logged in as an administrator you can access the Theme Customizer both from the front end and the Admin panel on your site. From the front end you’ll find the Theme Customizer on the WordPress menu under your site name.
In the Admin panel you can activate the Theme Customizer for the site’s current theme by going to Appearance > Themes and clicking Customize.
In either case, you are taken to the Theme Customizer for the current theme which consists of a collapsible left-hand sidebar with all the customization features and your site in preview mode on the right.
Using the Theme Customizer is really very easy. To get started simply open the feature you want to change in the sidebar, for example Site Title & Tagline, or, as seen below, Header Image, and make your changes. As you make changes to the different elements, the live site preview will change on the right to reflect these changes.
Once you’ve made your customizations and you’re happy with how the theme looks, go to the top of the customizer and click the Save & Publish button and your new settings will be activated on your site. If you don’t like your customizations, simply click Cancel and you are back to the Admin panel without any trace of anything having ever happened. Since this is a brand spanking new feature most themes only have support for the regular functions right now, but expect the Theme Customizer to showcase some pretty snazzy features once theme developers dive into the code for real.
Other WordPress 3.4 updates of note
WordPress 3.4 has two other cool updates under its sleeve:
1. If the theme allows it, you are no longer restricted to a specific size for the header image. As an example, that means you can upload a full-height image in the Twenty Eleven theme and have it take up most of your page if you want. I’m not sure that’s a good idea, but the option is there if you want to try it out. My recommendation is you try it in the Theme Customizer to see what it looks like first.
2. Image captions now allow HTML elements, so you can make fancy captions with text that has bold or italic emphasis, links, and all sorts of other interesting HTML touches.
