It uses Google Antigravity's coding agent and a /goal command to transform a basic tab interface into a neumorphic design, then addresses contrast problems identified by Lighthouse. After a correction, the application reaches a 100 accessibility score. ### Source excerpt The Angular team has called Angular Aria a set of customizable, fully accessible UI patterns. This is a strong claim, but in practice, how possible is it to heavily customize the components while maintaining accessibility features such as keyboard navigation and focus management? In this post, we're going to use Google Antigravity to put that claim to the test by updating a tab UI from generic styles to a neumorphism-based design. Motivation In the angular.dev documentation, the team has examples with a set of basic, Material Design-based, and retro styles meant to show developers what's possible with these new accessibility patterns. Here's the challenge: take the tabs basic styles example further by implementing the following neumorphism-inspired design. Here's a look at the UI before any changes: Angular Aria tabs component with basic styles applied The Lighthouse accessibility report shows a 100 score before making any changes: Accessibility score for the tabs based on the original styles Neumorphic designs are typically criticized for their poor accessibility. This experiment is designed to push the coding agent with complex CSS styles while stress-testing the customizability of Angular Aria tabs. Additionally, I'll ask the agent to update any accessibility issues that come up. Making the changes The styles for this UI are well organized, but require a lot of changes to achieve something like a neumorphic design. Instead of writing them by hand, Google Antigravity's coding agent can make the changes. Here's the prompt: /goal update the tabbed UI to be neumorphic style. The example UI is @example-ui.jpeg and the styles are in @src/app/app.css A few things to note here: This example used a reference image for inspiration (@example-ui.jpeg) to inform the designs. This example also uses the /goal command in Google Antigravity instructs the agent to work a task to completion without asking the user for immediate input. The Result Here's the resulting UI based on the ## How First Impressions Shape Client Choices and Views of the Web Industry DevFeed: [How First Impressions Shape Client Choices and Views of the Web Industry]() Original publisher: [Read original article]() Author: L.

They describe how writing, prototyping, browser testing, and research help deepen understanding, and argue that people should not be discouraged from sharing what they are learning. ### Source excerpt When I was learning CSS's grid feature (oh gosh, nearly ten years ago), I posted a few short videos talking about my understanding of the feature and how it worked. I was surprised to get scolded for sharing inaccurate information, "especially as a teacher". Wait, what?! Who, me?! I get things wrong all the time. That's part of learning. But it was the teacher remark that threw me because I've never considered myself a teacher. Yes, I've spoken at conferences and put on workshops but the label of teacher isn't one that I feel comfortable with. Perhaps I associate the word with all-knowing authority figures standing in front of a class and I'm far from all-knowing, or an authority, or have much of a figure. I have stood in front of classes, though. I imagine myself more like Stuart from the Mad TV sketch saying "look what I can do!" When I first got into web development, I built a web page that displayed a table pulled from a database. When I showed my friend, he wasn't all that excited. "Is that it?" It was, after all, just a table on a page. (Which, hey, it was 1996. Everything was just a table on a page.) This blog has been a 25+ year journey of me saying "look what I can do" over and over again. I enjoy the process of learning new things and sharing what I've learned. Writing about what I've learned helps me learn even more because I build prototypes and test in different browsers as I try to understand all the nuances of something in my effort to write about a topic. Even with the research and prototypes and testing and writing, I'll get things wrong but one of the things I have learned is not to admonish people sharing what they're learning, even if they get it wrong. We should all be forever a student. Have something to say? Tell me about it. ## MicroLighter: Syntax Highlighter DevFeed: [MicroLighter: Syntax Highlighter]() Original publisher: [Read original article]() Author: Geoff Graham Published: 2026-08-25T14:10:34Z Content type: article Language: en Sources: [CSS-Tricks]() Topics: [Syntax Highlighting](), [CSS](), [JavaScript](), [WordPress](), [Code]() Tags: [code](), [css](), [custom-highlight-api](), [javascript](), [links](), [resource](), [web](), [wordpress]() ### AI overview MicroLighter is a CSS-focused syntax highlighter for code blocks that uses Custom Highlights and aims to provide themes, line numbers, multiple-language support, semantic markup, and modular features with less JavaScript and fewer dependencies.
