What Themes Does in WordPress
Contents
A WordPress theme is a tool to change the layout and design of your website. Themes customize the appearance of your site, including the layout, typography, color, and other design elements.
Themes take the content and data stored by WordPress and display it in the browser. When you create a WordPress theme, you decide how that content looks and is displayed. There are many options available to you when building your theme. For example:
- Your theme can have different layouts, such as static or responsive, using one column or two.
- Your theme can display content anywhere you want it to be displayed.
- Your theme can specify which devices or actions make your content visible.
- Your theme can customize its typography and design elements using CSS.
- Other design elements like images and videos can be included anywhere in your theme.
- WordPress themes are incredibly powerful. But, as with every web design project, a theme is more than color and layout. Good themes improve engagement with your website’s content in addition to being beautiful.
How Theme Updates Work in WordPress?
WordPress comes with a powerful system to install updates for not just WordPress itself but for plugins and themes as well.
Your WordPress website regularly checks for updates and display them under Dashboard » Updates page.

When a theme update becomes available, you’ll also see a notification on the Appearance » Themes page.
Which are really important for the security and performance of your WordPress website. Aside from security and bug fixes, theme developers can also introduce new features with these updates.
Just click on the update button to install the new version, wordPress will then download the theme package, unzip it, and replace the old files with the newer version.
This will overwrite all old theme files installed on your website. If you manually added custom code to your WordPress theme files, then you’ll lose those changes.
Customization you can lose during WordPress updates
If you have added any code to your theme’s functions.php file, then it will disappear. Any CSS changes that you have added directly to your theme’s stylesheet (style.css) file will also be wiped off.
Popular WordPress themes like Astra, Divi, Beaver Builder, Elementor, etc now come with companion plugins. These plugins are used to add extra features to your theme. Any theme changes made using these companion plugins are also not affected by the theme update.
If you customize your WordPress layout using a WordPress page builder then those changes will also not be impacted.
Any other features that you have added to your website using a plugin are also safe. For example, your WordPress contact forms, Google Analytics, email newsletter popups, and more.
