  • Gridlex

    Based on Flexbox (CSS Flexible Box Layout Module), Gridlex is a very simple css grid system to quickly create modern layouts and submodules. How it works? The concept is simple: you need to wrap your .col in a .grid. That's all. Gridlex is ready to use "out of the box" in CSS, with all the vendor prefixes needed, or you can use Less or Sass files included

  • Tailwind CSS

    Tailwind is different from frameworks like Bootstrap, Foundation, or Bulma in that it's not a UI kit. It doesn't have a default theme, and there are no built-in UI components. On the flip side, it also has no opinion about how your site should look and doesn't impose design decisions that you have to fight to undo.

  • Juiced (a Flexbox CSS Framework)

    Juiced has many of the same layout features that you know and love, but improves upon them with better mobile targeting, custom column ordering, better alignment options, understandable HTML, and less boilerplate styles. Juiced builds on some of the awesome things found in Foundation and Bootstrap but it does not come with heavy styling, opinions, or a large codebase. Also it left out JavaScript. Juiced is built on Flexbox.

  • 960 Grid System

    The 960 Grid System is an effort to streamline web development workflow by providing commonly used dimensions, based on a width of 960 pixels. There are two variants: 12 and 16 columns, which can be used separately or in tandem. The premise of the system is ideally suited to rapid prototyping, but it would work equally well when integrated into a production environment. There are printable sketch sheets, design layouts, and a CSS file that have identical measurements.
