Why good code needs defending Good code quite frequently comes under fire. Managers explicitly or implicitly pressure developers to cut corners in order to “move fast”. And sadly, even programmers sometimes argue against writing good code. They say things like “it doesn’t always need to be perfect, because after all we need do to ship”. …

With screens available in any size you can imagine, it's time to shift our approach towards responsive design – the era of breakpoints is over and the era of fluid design is here. Modern CSS has fantastic support for responsive design that ensures you won't ever have to write a media query again (if you don't want to).

Could we drop Symbols from Ruby? Don’t know about you, but I personally have been hit a least a dozen times by bugs caused by strings vs symbols distinction. That happened in my own code, and it happened when using some other libraries as well. I like how symbols look in the code, but I don’t like the specific distinction that is made between them and strings. In my (perhaps controversial opinion) they introduce more problems than they solve.

There are a number of very robust charting libraries on the market. Some are commercial. Some are free. You should use them. Every once in a while though, you need to roll your own. Not to worry!

Writing CSS has probably never been more fun and exciting than it is today. In this post we’ll take a look at common problems and use cases we all have to face in our work and how to solve them with modern CSS. If you’re interested, we’ve also just recently covered [CSS auditing tools](https://www.smashingmagazine.com/2021/03/css-auditing-tools/), [CSS generators](https://www.smashingmagazine.com/2021/03/css-generators/), [front-end boilerplates](https://www.smashingmagazine.com/2021/06/useful-frontend-boilerplates-starter-kits/) and [VS code extensions](https://www.smashingmagazine.com/2021/05/useful-vs-code-extensions-web-developers/) — you might find them useful, too.
