It’s dangerous to make assumptions about how users are interacting with and viewing your website. For instance, desktop users who zoom in on websites will wind up activating the mobile view. And some mobile users navigate with a keyboard.
Rather than “Read More” links, be specific: “Read more about ---.” This is important for users with screen readers who are unable to see the association between the “read more” link and the content it references. You can visually hide “---” so that only screen readers will detect it.

Front-end performance is also a critical priority for Zen. That’s why Zen 5’s markup and CSS footprint is so small. After turning on Sass production-mode compilation, the total CSS is only 14k; this includes the layout, vertical rhythm support, print styles, all the appropriate vender prefixes (like -o and -khtml), CSS3-prettified tab styling and the 3 menu images that are included via Data URIs into the CSS. Zen includes no images and only 2 JavaScripts (which are only loaded conditionally by IE8 and lower, but also minified and pre-aggregated together).
