Hello,
Everything has been laid out transparently on the Live Previews. Since this is a Template Package of more than 1200 Templates, different CSS Codes for different Templates is not something that is practical to implement and will cause a lot of issues when we implement updates. Additionally, if you would like to add a Block to the existing templates, you will need to find and add the CSS and JS Codes manually, which is a hassle.
Since Canvas is a Multi-Purpose Template, all the CSS/JS are provided by default. However, you can simply delete the js/plugins.min.js JS File Linking from your HTML File and our smart JS Functions will automatically enable Lazy Loading for JS Files which will load according to the Elements on the Page, so no extra JS Codes. More details here: http://docs.semicolonweb.com/docs/getting-started/javascript/ . For CSS, you will need to use the style-import.css File to include/exclude CSS according to your needs. Other Files can be removed manually.
Additionally, we already have a Powerful Tool available for sorting the files: http://docs.semicolonweb.com/docs/getting-started/installation/#docs-snippet-package-generator, so you will not need to delete the Files manually. Simply use the Package Generator to Choose the HTML Files you need for your Project and a Package will be generated for you based on the Files needed for the chosen HTML Files.
Hope this Helps!
