I remember arguments about whether this whole CSS thing was a good idea at all. I was quickly convinced, mostly due to the ability to easily change…

The Best Cocktail in Town

November 18th, 2019

I admit I’ve held in a lot of pent-up frustration about the direction web development has taken the past few years. There is the complexity. It requires a steep learning curve.

Finally, it Will Be Easy to Change the Color of List Bullets

November 14th, 2019

In my germinating years, the general advice was this: <ul> <li><span>List item</span></li> <!– … –> </ul> li { color: red; } /* bullet */ li span (color: black; } /* text */ Not terrible, but not great. You’re “resetting” everything at the span level, so it gets more complicated the more you do. Things are…

Oh Hey, Padding Percentage is Based on the Parent Element’s Width

November 13th, 2019

I learned something about percentage-based (%) padding today that I had totally wrong in my head! I always thought that percentage padding was based on the element itself.

Two-Value Display Syntax (and Sometimes Three)

November 8th, 2019

You know the single-value syntax: .thing { display: block; }. The value “block” being a single value. There are lots of single values for display. For example, inline-flex, which is like flex in that it becomse a flex container, but behaves like an inline-level element rather than a block-level element. Somewhat intuitive, but much better…
