Using the WordPress editor, you can edit a template to add a sidebar to your pages. You will see a dark grey border around this area. Click on the block to select it, and you will be able to see the content of the template. If you need to change more than one element on a page, you can select a page-specific template. You can then edit this template by dragging and dropping existing blocks or adding new ones.
To edit a WordPress template, you can first go to the Template Editor, which is an optional feature for classic themes. This tool is similar to an image editor, but it lets you create block templates to change the layout of your whole page. Block templates do not use the PHP template, but you can use any post editor blocks. You can also edit the footer and header elements. Once you have finished, you can click on the Site icon to exit the editor.
Changing the theme will change the appearance of your site, depending on how it looks. In this section, you can set the size of the title block, the appearance of the side columns, and the font family. You can also apply various styles to the template. Finally, you can set the information in the footer of your site. For advanced users, you can edit CSS styles. You can even select a different color scheme if you wish.
