Blogger GuidesHow to change a Blogger theme and customize colours and fonts
A theme sets the whole look of the blog. The Customize screen lets you change colours, fonts and widths without touching code.
Choose a theme
- Sign in to Blogger and choose the blog.
- Click Theme in the left menu.
- Choose a theme and click Apply at the bottom.
Before you apply a new theme, save the old one: at the top right, click More, then Backup, then Download. Blogger's help describes the same step.
Customize the look
- In Theme, under "My theme", click Customize.
- Use the left menu to change the background image and other settings (the list depends on the theme).
- Click Save at the bottom right.
For fonts and colours of text, click Advanced in the left menu and choose a format for your text. You can choose different fonts, colours and sizes for different kinds of text. Save when you finish.
Dynamic views
Blogger's help describes Dynamic views themes as themes where each post displayed counts as a page view, and where your readers can change their default view. Some features of Dynamic views can be used without changing the theme. If you want a classic fixed design, choose one of the non-dynamic themes.
Where gadgets fit in
A gadget is an element such as an archive, a list of labels or a profile. Add them in Layout: click Add a Gadget in the area you want, choose the gadget and click Add, then Save at the bottom. To change a gadget, click Edit. See the page on layouts.
Checks after a change
- Look at the blog on a phone and on a computer. A theme that looks good in the preview can be crowded on a small screen.
- Open a post, a page, the home page and a label page. They can look different.
- Look at the Layout page: some themes have different areas, so gadgets can move.
- Check the colours of links and text for readability, in particular text on coloured backgrounds.
When to leave Customize and use code
Customize changes what the theme author planned to be changeable. For anything else (a custom font, spacing, hiding a part of the page) you add CSS or edit the HTML. The next page explains how to do that safely.
Will changing the theme delete my posts?
No. Posts and pages stay. Gadgets in the layout may move or disappear, which is why you save the old theme first.
Can I go back to the old theme?
Yes, if you saved it: use Restore in the Theme menu. Without a copy you can only choose a new theme again.
