In reply to Isabel.

I'm conservative. I do not want no trouble. All too often in the past I found myself high and dry when a theme developer decided to stop maintaining their theme. So my go-to themes are the twenty series from the golden age of WP. "Twenty Ten" when WP3 made WP really good through "Twenty Seventeen," the last one before WP went off the rails. These 7 themes represent much of the best of WP, provide a range of design choices, are mostly solid, are regularly updated (Twenty Ten was updated in July 2021), and in use by millions of websites.

When I look at a theme I do not look at the colors, fonts, or graphics because all are easily changed using CSS. I look beneath that to find the "bones," also called a "wireframe" diagram. You can use the bookmarklet Wirify to turn any web page into a wireframe. https://www.wirify.com Wirify's is a good place to start, good because it hides the non-essential, but also too detailed and literal. Step two is to mark up what it produces to identify the major page elements: headers, footers, content area, sidebars, etc.
