    Cerberus

    Cerberus

    Patterns for responsive HTML email templates and newsletters

    Coding regular emails is hard enough by itself. Making them responsive shouldn’t add to the headache. A few simple, but solid patterns are all that’s needed to optimize emails for small screens. It’s just a few responsive email patterns that go a long way. The code blocks are compartmentalized so they may be used, removed, combined, and nested to build an email. Each template contains code comments and has good support among popular email clients. Cerberus is a small collection layout patterns for HTML email. The code is meant to be edited, adapted, and built upon. The code is compartmentalized and annotated in an effort to explain what’s happening so you can add, edit, and remove code with some confidence. This has been tested in all “popular” email clients, but not every email client out there. Good for simple layouts such as transactional and single-column emails.
