    Project mention: 500 open-source components for TailwindCSS | | 2023-10-30

    I'd like to share my latest discovery with you. TW Elements is currently, the most popular 3rd party UI kit for TailwindCSS with over 10k Github stars. It's a huge collection of stunning components made with attention to the smallest detail. Forms, cards, buttons, and hundreds of others. All components have dark mode and very intuitive theming options. The project is supported by an engaged community on GitHub, I recommend you check it out and join one of the many discussions. You will find installation instructions here, and you can track the progress of the project live here. The project was kickstarted by @mdbootstrap, a group of open-source developers behind MDB UI Kit - a high-quality UI kit for Bootstrap, and also behind MDB GO - hosting and deployment platform. I highly recommend you to check it out!

  • Milligram

    A minimalist CSS framework.

    Project mention: Concrete.css | | 2024-02-08

    I had been using similar projects such as skeleton[0] and milligram[1] for small experiments such as repfl[2], and wanted to create something similar that I would find aesthetically pleasing and that would fit in as little space as possible. The current version of concrete.css is less than 1kb minzipped!

  • Tufte CSS

    Style your webpage like Edward Tufte’s handouts.

    Project mention: Concrete.css | | 2024-02-08

    As it is often said in various designer forums, please avoid pure white (#FFFFFF) on black (here #111111), as it makes the text glow for the human eyes (therefore making it unreadable for long text). Instead, try to lower a bit the contrast on the text color.

    Also, the dispositions for the buttons at the beginning (GitHub, NPM, ...) are not adjusted correctly for keyboard navigation (each button requires two tabs).

    Appart from that, I do like a minimalist stylesheet, so I will also recommend Tufte CSS [0] for readers.

    Project mention: Ask HN: I'm bad at design, which stops me from finishing side projects. Advice? | | 2023-11-22

    Buy a bootstrap theme, they're cheap and they offer a lot out of the box. Better solution than bare tailwind, which actually requires you to know how to design. I used tailwind on my personal website, result was good but I had to do a lot more than if I used a bootstrap theme.

    You make your app ui work within the boundaries of your bootstrap theme and you're good for 96% of the design stuff.

    If you don't want to even learn bootstrap css classes and stuff, consider

    It's amazing, you drop it and you have a theme based on the html only. I use this mostly for prototyping though

  • open-props

    Project mention: Why Tailwind Isn't for Me | | 2024-01-26

    I don't quite get the hate for having CSS in another file. Do you also put all your react stuff in one single file ? That same logic and argument can be applied against all modularization.

    And really 20-50 tailwind classes in a single element is VERY hard to read and keep in mind. No - it does not make things clear or understandable. One tends to need to re-read and scan over from the beginning and eyes glaze over. Esp if some elements only vary with a few classes missing. I guess it works for people with very high attention to detail and high amount of working memory. I only find it personally frustrating.

    Maybe tailwind css works for some bright people. I did try it for a couple of projects and only felt pain.

    However, the "atomic css" philosophy behind tailwind is great. I find framewroks like far better to use.
