A CSS-Only Star Rating Component and More! (Part 2)

We ended with CSS code that we can easily adjust to create component variations, including a heart rating and volume control. This second article will study a different approach that gives us more flexibility. Instead of the border-image trick we used in the first article, we will rely

Maybe don’t use custom properties in shorthand properties

by: Geoff Graham Thu, 06 Mar 2025 16:33:55 +0000 Manuel Matuzović: This easily qualifies as a “gotcha” in CSS and is a good reminder that the cascade doesn’t know everything all at the same time. If a custom property is invalid, the cascade won’t ignore it, and it gets evaluated, which invalidates the declaration. And if we set an invalid custom property on a shorthand property that combines several constituent properties — like how background and animation are both shorthand for a

FOSS Weekly #25.10: Skype is Dead, GNOME 48 Features, Ubuntu Versions, Nano Guide and More Linux Stuff

by: Abhishek Prakash Thu, 06 Mar 2025 05:27:13 GMT Skype is being discontinued by Microsoft on 5th May. Once a hallmark of the old internet, Skype was already dying a slow death. It just could not keep up with the competition from WhatsApp, Zoom etc despite Microsoft's backing. While there are open source alternatives to Skype, I doubt if friends and family would use them. I am not going to miss it, as I haven't used Skype in years. Let's keep it in the museum of Internet history. Speaking

Grouping Selection List Items Together With CSS Grid

by: Preethi Wed, 05 Mar 2025 13:16:32 +0000 Grouping selected items is a design choice often employed to help users quickly grasp which items are selected and unselected. For instance, checked-off items move up the list in to-do lists, allowing users to focus on the remaining tasks when they revisit the list. We’ll design a UI that follows a similar grouping pattern. Instead of simply rearranging the list of selected items, we’ll also lay them out horizontally using CSS Grid. This further d

Top 7 Best Open Source Skype Alternatives In 2025

by: Sourav Rudra Tue, 04 Mar 2025 11:04:00 GMT May 5 2025, is the day Skype will cease to exist as Microsoft retires it, pushing people to switch to their Teams offering. The death of Skype was a slow one, but one that has been coming for quite some time now.

Chris’ Corner: Color Accessibility

It’s a nice option to have, but I fin

Functions in CSS?!

I know, it isn’t the most pleasant feeling to finish reading about a new feature just for the author to say “And we’ll hopefully see it in a couple of years”. Luckily, right now you can use an (incomplete) version of CSS functions in Chrome Canary behind an experimental flag, although who knows when we’ll get to use them in a production environment. Arguments, defaults, a
