Frequently Asked Questions

What should I check before buying an HTML template?

License scope (personal vs. commercial, single-project vs. unlimited), code quality (semantic markup, no inline styles everywhere), and whether it's actually been updated recently — an unmaintained template can carry outdated, insecure dependencies even if the design still looks current.

Is a free HTML template actually free?

Often not in the way it first appears — attribution requirements, missing commercial-use rights, and unmaintained code are common hidden costs. Check the license file specifically, not just the download page's marketing copy.

Do I need to know how to code to customize a template?

Basic HTML/CSS familiarity helps, but a well-built template only requires editing text, swapping images, and adjusting a handful of CSS custom properties for colors and fonts — not writing new code from scratch.

What's the difference between a template and a framework?

A framework (like Bootstrap) is a system of reusable classes and components you assemble yourself. A template is a finished page (or set of pages) already assembled — often built using a framework underneath, but ready to use with content swapped in rather than built up from primitives.
