Bolt.css – Another classless CSS library

In plain words

Bolt.css is a classless CSS library that styles HTML elements without requiring custom class names. Launched in 2022, it automatically applies styling to standard semantic HTML tags, making it useful for developers who want presentable websites with minimal CSS setup. It's designed for anyone building simple projects, documentation sites, or prototypes where writing custom classes would be unnecessary overhead.

Basic styles for HTML Elements. Providing a mostly-reasonable set of styles without classes. Use it for simple static sites or as a starting point and add your own classes. This is not a complete solution with layout grids, components, utility classes, and the like. I used the fantastic HTML Elements Reference on MDN and modified it as needed. Grab the bolt.css stylesheet and add it manually to your app/site. Alternatively, drop this right into your <head> to use it via a CDN. <link rel="stylesheet" href="https://unpkg.com/boltcss/bolt.min.css"> Salamanders are a group of amphibians with a lizard-like appearance, including short legs and a tail in both larval and adult forms.

  I 3D scanned the interior of the Great Pyramid at Giza▲1,752

  Hey HN, I 3d scanned the interior of the Great Pyramid &#x2F; Khufu's pyramid for the Giza Project this summer and just finished the guided version to share. Would love feedback and&#x2F;or problems you encounter. I used both a Leica BLK 360 and Matterport Pro 2 to do the scanning and the Matterport SDK for the web viewer. Matterport's web display with Three.js has been the most accessible to a wide audience in the past (previous iterations are in Unity and Unreal, but difficult to download over slower connections). I've been interviewing social studies teachers around the 6th grade level to…

  America – Road Trip Simulator▲663

  APIs are a little like the open road—always waiting, full of opportunity, but hardly utilized. So here’s America, composed of several APIs that paint a vivid, real-time picture of a good old-fashioned road trip. Get local classifieds and photos. Tune into local radio stations. Talk wit other drivers. And more. Exploring the country by car was an invaluable experience for me during my time in the states. I’ve since moved to Barcelona, and find myself missing the territory. This is my attempt at recreating the magic.
