I am using bimber wordpress theme (demo link - hidden link) with the toolset plugin.
I have created custom post types. When I am trying to display the custom post type archive page, it is not using the css of the main theme to display like it is showing in posts archive page. Any help on how to make that happen .i. to show the posts UI like the posts archive page?
The PHP templates of a theme determine the HTML markup that will be output on a particular page (including an archive), and the theme CSS will target elements on the page based upon this expected markup structure.
So to recreate the look of a theme's built-in archive when creating a custom archive using Toolset you need to recreate that structure (including adding the classnames that the theme applies to HTML elements).
When you create a custom archive with Views, it is just a means of spitting out markup that you specify for each post.
The one thing you don't have much control over is that the archive results will be wrapped inside a container div generated by Views, but otherwise you can include whatever markup you need.
You need to either user the browser dev tools to examine and reverse-engineer the markup structure used by the theme, although it would be more direct to examine the PHP template for the archive itself (probably archive.php).
You can add markup outside of the wpv-loop tags for container markup that isn't repeated for each post, whereas markup that appears inside the wpv-loop tags of the View (directly, or indirectly via an included template) will be output for each result.
