What: When using CSS columns, the content doesn’t always line up at the top of each new column. The more columns you have, the more likely you are to run into this problem, especially if you’re using column-fill: balance. And the problem seems to happen in Chrome-based browsers, in Safari and in browsers on iOS.

Jittery Scrolling
What: Jittery Scrolling, or very slow scrolling in Chrome-based browsers. It’s caused by too many paint operations when scrolling, in my particular case caused by an SVG set as a background-image with background-size: cover and background-attachment: fixed.
Media Queries for Input Devices
What: Since not every touch enabled device is a handheld device, checking for size and checking for touch should be handled separately, since the changes to the design and functionality they require are not the same.
How: You can use media queries.
scroll-margin-top
What: CSS-Tricks just posted about this last Friday and since I could have used this that day (!) but didn’t find it until now, I’m adding a note here for myself:
You have a page with a table of contents (with links), or you have a one page website with in-page navigation and you have a fixed header — when you click a link the content scrolls up too far and is hidden by the fixed header. This is not a good user experience, and you can improve it with scroll-margin-top in Firefox and Chrome-based browsers…
Counting Down an Unordered List
What: You have an unordered list and you want to turn it into an ordered one through CSS
How: You can do this with CSS 2.1 and the counter element. Yay! I love CSS.
Always Include Widows and Orphans
What: Widows and orphans in CSS refer to leftover lines at the beginning or ending of a page, when you’re printing a website, or to the leftover lines at the beginning or ending of a column when you’re creating a multi-column layout.
Auto Sizing Font-sizes
What: Changing the font-size and the line-height based on the width of the viewport but without using media queries, to create a smoother experience (with less work).
Writing less.
A nice old (2016) video of a talk by Heydon Pickering about writing less code. It’s smart, funny, and I agree.
Fake centered fixed width
What: Say the background of your website is white and you want, for example, a different color header, full width, with content inside the header that’s contained at a lesser width, and centered. Common enough scenario and usually created with one HTML-element (div, section, …) at full width and with a colored background and one HTML-element (div, article, …) with a fixed width and centered, holding the content.
Styling placeholder text
Not something new I learned, more something I keep forgetting over and over.
::placeholder to change how placeholders look. You’d think I’d remember something so obvious…
If it’s not working, this post over at CSS-Tricks may have some more information on why.
(Actually, what that post taught me, is that there is a difference between pseudo elements and pseudo classes!)
