 A simple layout looks good at a variety of window sizes, rendering responsive layout changes unnecessary. Textual websites really don't need more than a single column; readers should be able to scan a page top-to-bottom, left-to-right (or right-to-left, depending on the locale) exactly once to read all its content. Verify this using the horizontal-line test: mentally draw a horizontal line across your page, and make sure it doesn't intersect more than one (1) item. Keeping a single-column layout that doesn't require responsive layout changes ensures smooth window re-sizing.

 In addition to standard testing, I recommend testing with unorthodox setups that are unlikely to be found in the wild. If a website doesn't work well in one of these tests, there's a good chance that it uses an advanced Web feature that can serve as a point of failure in other cases. Simple sites should be able to look good in a variety of situations out of the box.
 
 Your page should easily pass the harshest of tests without any extra effort if its HTML meets basic standards for well-written code (overlooking bad formatting and a lack of comments). Even if you use a complex static site generator, the final HTML should be simple, readable, and semantic.
