Definition
Not all clients support CSS linear gradients. A background-color behind the gradient ensures basic fidelity.
Best Practices
- Always declare a background-color before the gradient.
- Test Outlook, which generally ignores gradients.
- Keep the fallback colour close to the gradient start or end.
