There is a sentiment that leaving math calculations in your CSS is a good idea that I agree with. This is for math that you could calculate at authoring time, but specifically chose not to. For instance, if you needed a 7-column float-based grid (don’t ask), it’s cleaner and more intuitive:

.col {
/* groan */
width: 14.2857142857%;

/* oh, I get it */
width: calc(100% / 7);
}

You could probably prove that the calc() takes the computer 0.0000001% …

Flickr announced not long ago that they are limiting free accounts to 1,000 photos. I don’t particularly mind that (because it seems like sound business sense), although it is a bit sad that a ton of photos will be nuked from the internet.

I came across this amazing Dribbble shot by Jakub Reis a while back. It caught my eye and I knew that I just had to try recreating it in code. At that moment, I didn’t know how. I tried out a bunch of different things, and about a year later, I finally managed to make this demo.

I learned a couple of things along the way, so let me take you on a little journey of what I did …

We recently covered this exact same thing, but from the perspective of a bunch of developers.

Chris Ferdinandi weighs in:

The least important skills for a front-end developer to have are technical ones.

The nuances of JavaScript. How to use a particular library, framework, or build tool. How the cascade in CSS works. Semantic HTML. Fizz-buzz.

Chris takes that a little farther than I would. I do think that with an understanding of HTML, CSS, and JavaScript, the …
