Create a child theme based on an existing parent theme in WordPress and change the functionality, presentation, or styling of your website. In this course, author Morten Rand-Hendriksen shows how to use the default WordPress theme, Twenty Twelve, as a basis for a new child theme and add custom menus; new headers, sidebars, and footers; and index pages with widgets and pagination to your site. The course also demonstrates how to add a responsive welcome message to your front page using PHP and jQuery, and how to edit the many templates found in a WordPress theme. Morten explains how to perform these changes using any code editor, the developer tools in the Chrome browser, and WordPress.
By following this course, you've now created an advanced child theme based on the Twenty Twelve theme, and added lots of interesting functionality. And I also hope you've walked away with some information about how you can use the same techniques to alter other themes if you want to use them. Before we wrap up, I want to impart on you some very important information about updates. And this is something I tell everyone who works with WordPress. When you have a WordPress site, it's extremely important that you always keep it up-to-date.
If you don't keep updating your site, you run the risk of either missing out on important updates and features, or even worse, you might leave your site open for attacks. It's very easy to update both WordPress and also update themes and plug-ins. You just have to remember to keep in mind that you need to check if they need to be updated. And because you're working with a child theme, it's actually completely safe to update the parent theme for your child theme, because as I've said several times throughout this course, if you update the parent theme, nothing really happens to the child theme.
You just add a new functionality and new security features. So how do you know what needs to be updated? Well, WordPress makes it very easy for you. Once you're logged in, if you're on the front page, you'll actually see this recycling sign up here, and it will tell you if you need updates. Right now, I need to update one plug-in and one theme. If I am on the back end and I go to the Dashboard, you'll see, under Dashboard, we have a link that says Updates and it will tell you how many items need to be updated.
If I go to the Updates link, I'll get all the information about the different versions I have installed. Here you see I'm currently running the latest version of WordPress. There's one plug-in that needs to be updated, and I also have one theme that needs to be updated. Updating WordPress, updating plug-ins, and updating themes is very easy. All you have to do is select them and click Update, and WordPress pretty much does it for you. In some cases, the server will prevent you from doing this automatically. And in those very rare cases, you need to do the update manually.
But in almost every case, the update is automatic. If you see that there is an update to WordPress or to a plug-in or to a theme, apply the update right away. Chances are you'll add a new feature that will make your site even better. Now you have a fully built-out child theme that you can play with, you can augment, and you can change into anything you want. Thank you for taking part in this journey through child themes with me. This is Morten signing out!
