Join Morten Rand-Hendriksen for an in-depth discussion in this video Installing and activating Twenty Fifteen, part of Start With a Theme: Twenty Fifteen.
- When WordPress 3.0 was released back in June of 2010, it came with a new default theme, named Twenty Ten. And this started the trend of releasing a new default theme for WordPress for every year. Always named after the year they were released. The original Twenty Ten theme was created to set a new standard for how themes for WordPress were built. In 2011, this process was evolved to also include best-practice features for new enhancements in WordPress, like featured posts, and featured images.
Then, in 2012, a whole new theme was created, focusing more on people who use WordPress as a content-management system. This theme, called Twenty Twelve, has also become the baseline for when you want to create themes that support child themes. It's very easy to build a child theme on top of, and it's also a good template if you want to build a theme that will then have child themes built on top of it. In 2013, the project took a whole new direction, and created a highly opinionated theme that was focused mainly on bloggers.
This was also the first default theme that focused heavily on post formats, what you can see here in the different color-coded posts. Now, this was a very popular topic at the time, but post formats have fallen more into the background of WordPress, and are no longer focused on in these default themes. The Twenty Fourteen theme took a whole new direction again. This time focusing on the very popular magazine-style layouts. And many will argue that of all the default themes, Twenty Fourteen is the most opinionated.
This is a theme that there's been a lot of discussion about. it's great if you want a specific style of site, but a lot of people don't really like it because it has such a strong opinion about how to present content. And this leads us to Twenty Fifteen, the theme I'll talk about in this course. The Twenty Fifteen theme in many ways goes back to the roots of the year-theme project. It is a blogging theme, and focuses on current web standards. You can see that its flat design, what is popular right now.
And it's also heavily focused on accessibility, meaning anyone should be able to access the content put into this theme. It's very easy to use, it doesn't have a lot of configuration settings, and presents your content in an easily-readable, and easily-accessible way. The Twenty Fifteen theme was released with WordPress 4.1, which came out in December of 2014. So, if you installed a fresh version of WordPress, and it was WordPress 4.1, the Twenty Fifteen theme is what you'll see when you visit the front-end of your site for the first time.
However, if you're upgrading WordPress from a previous version, Twenty Fifteen will likely be installed in your site, but you have to activate it from the back-end. So, if that's the case, you need to go to the dashboard, go to "appearance", and "themes", and here you should see Twenty Fifteen as an option. If you don't see Twenty Fifteen as an option, you can always go and click "add new", and search for Twenty Fifteen, and then you'll find it, and be able to install it directly into your site.
Once Twenty Fifteen is activated, you can see it on the front-end of your site, and you'll see right away that this really is a content-focused theme that's great for bloggers.
