Improving UX Through Front-End Performance

by Lara Swanson · 30 Comments

Adding half a second to a search results page can decrease traffic and ad revenues by 20 percent, says a Google study. For every additional 100 milliseconds of load time, sales decrease by 1 percent, Amazon finds. Users expect pages to load in two seconds—and after three seconds, up to 40 percent will simply leave. The message is clear: we must make performance optimization a fundamental part of how we design, build, and test every site we create—for every device. Design for performance; measure the results.

The Era of Symbol Fonts

by Brian Suda · 43 Comments

Welcome to the third epoch in web performance optimization: symbol fonts. Everything from bullets and arrows to feed and social media icons can now be bundled into a single, tiny font file that can be cached and rendered at various sizes without needing multiple images or colors. This has the same caching and file size benefits as a CSS sprite, plus additional benefits we’re only now realizing with high-resolution displays. Discover the advantages and explore the challenges you’ll encounter when using a symbol font.

The Couch Cone of Silence

About five years ago, I bought a cushy couch for my office. (Okay, yes, I did get the model that could flatten into an emergency nap station, but let’s just say that I plan for contingencies—it sounds more professional that way.) Our projects required a lot of office-to-office visiting to discuss situations in person, and eventually, said couch (and therefore, my office) became a veritable beacon, attracting anyone looking for an excuse to decompress. Such is the life of a one-couch, 50-chair business.

Learning to Be Flexible

As a freelancer, I work in a lot of different code repos. Almost every team I work with has different ideas of how code should be organized, maintained, and structured. Now, I’m not here to start a battle about tabs versus spaces or alphabetical order of CSS properties versus organizing in terms of concerns (positioning styles, then element layout styles, then whatever else), because I’m honestly not attached to any one system anymore.
