Build me a simple learning project for HTML and CSS called TecBoard.

I want a clean website that looks like a tech themed landing page, with a nice header, a main hero section, a few content blocks, and a footer. Keep it simple and easy to understand, since this is for practicing HTML and CSS. Make it look polished, modern, and responsive on phone and desktop.

Use separate CSS when it makes sense, but I also want a couple of example pages that show different ways of styling the same content, like inline styles and internal styles, so I can compare them. Add the images, icons, and fonts in a way that fits the design. If you need to check current best practices or look up a detail, feel free to do that online.

Please make the result feel like a real small project I could open in the browser and use to learn from.
