How can I use the Blogger Layouts features?
1- Go to the dashboard, and click on the template button.
If this link says Layout instead, then it's already upgraded and you can skip the rest of these steps.
2- On the Template page, search for the navigation link in the tab that says customize your design and click on it.

3- Then you will get a message explaining that Blogger will make a backing of your recent template and change it to an upgraded one. Click on the Upgrade Your Template button.
4-select your default template designs. Click Save Template when you've made your choice.
You'll end up on the new Page Elements tab, where you can start arranging things however you like.
You can easily edit and customize the colors, fonts, header and sidebar of your blog with Blogger's Layout feature. To customize your blog's layout, go to the Layout Page Elements tab in blogger.
How to arrange elements in your template?
Arrange the elements in your template as you want. You just have to click on the element that you like to move and "drag and drop" it where you want it to be. You can move your page elements to the bottom of the page, anywhere in your sidebar, or below or above your blog posts. (Note: you can move all elements except your navbar, blog posts and header in some templates.)
Editing elements in your template
Navbar: choose the color you want for your navbar.
