You can change the way your blog appears and functions through Themes.
We have some tips on Testing and Changing Themes which will help in planning your change.
Glow Blogs supports 14 different themes. Most of these are standard WordPress themes. WordPress has documentation on some of these:
Default themes – WordPress.org Documentation In addition we have the older Twenty Fourteen and Twenty Thirteen themes.
As of June 2023, we have 2 themes that support Site Editing, Twenty Twenty-Two and Twenty Twenty-three.
We also have Agama Pro and the Make theme. These are third party themes with some different methods of customisation. The make theme has its own page builder. You cannot use the newer blocks editor with the make theme. You can use the older classic editor or its own Post Builder. Be careful when choosing the Make theme, it allows advanced page layout in its page builder but you will not be able to use blocks.
For sites that need more complex layouts we would now recommend using the block editor and the Twenty Twenty-three theme with Site Editing.
The Site Editor allows you to design the entire site including the header, footer, and everything in between, with blocks. It gives you greater control over how your site looks.
When you set up a new blog it has the theme TwentyFourteen applied as standard. Some themes are suitable for different purposes.
If you are switching themes you may lose any widgets you have set up. You can save the content of these widgets by dragging them to the Inactive Widgets section of the Widgets area of the dashboard before you change theme.
You may also have to place you menus after switching theme. Your menus will be the saved but they will not appear on the blog until you set their location.
Themes can be managed via the Theme section of the dashboard or via the Customizer. We cover the dashboard method below.
Themes are managed from the Theme page of the Appearance section of the dashboard .
This page shows the current theme  and Thumbnails of all of the other themes. You can Preview each theme and activate them from the links under each thumbnail. clicking on the thumbnail will preview that theme.
Example of some themes.

Make Theme The Make them supports a page builder when you select that from the template chooser for a page you can add various sections to your page: banners, column sections and galleries. The Make these using quite a different way of adding content. It gives greater control and has more features than the classic editor and themes. It will not, as of 2023 allow you to use the block editor.
