What are WordPress themes?

Learn everything about designing your WordPress blog with themes and design templates - More info in the WordPress Tutorial from checkdomain.net

WordPress themes are design templates for WordPress blogs. The themes determine the appearance of the entire WordPress website and can be managed centrally in the WordPress backend. There are many free and paid WordPress themes that can be installed via the backend or FTP. By separating design and content, it is possible to display the same content with a different theme, i.e. a different design.

WordPress Theme Administration

WordPress themes are administered centrally in the theme administration. In the backend you will find the theme management under the menu item "Design" and there under the sub-item "Themes".

The WordPress version 5 already comes with four themes:

  • Twenty Nineteen
  • Twenty Seventeen
  • Twenty Sixteen
  • Twenty Fifteen

The theme named "Twenty Nineteen" is the most recent theme, the other themes work as well, but are a bit older and may have problems with the latest plugins and widgets

WordPress Theme Preview

Each theme can be tested with a "live preview". To do this, simply go to a theme with the mouse. A corresponding button "Live Preview" will appear. If you click on the button, the selected theme opens with the current contents in preview mode.
