As the saying goes: to do a good job, must first sharpen its tools, the project is tight, the framework is still very necessary.

1. Bootstrap

Bootstrap, originally called The Twitter Blueprint, was created as a tool for internal team use. It is one of the best known front-end frameworks. Since its public release, Bootstrap usage has increased year by year.

Bootstrap provides design templates for alarms, buttons, rotation, drop-down menus, and forms. With Bootstrap’s mobile-first feature, you can easily create responsive layouts that ensure design consistency across multiple devices.

2. Skeleton

Skeleton claims to be a “simple, responsive template”. Since this framework is only about 400 lines of code, it is better suited for small projects and application scenarios where developers need to create lightweight content.

Due to its simple layout, Skeleton is a good choice for those just starting out with a front frame. Of course, it’s the lack of CSS design templates, preprocessors, and overall functionality that makes a limited Skeleton unsuitable for large projects.

3. ZURB Foundation

If you are looking for a responsive front-end framework, ZURB Foundation is the place to be. The framework will allow you to create code and prototypes for various production environments for all devices. By supporting popular frameworks with “Barebone Structures”, ZURB Foundation enables users to rapidly prototype products using simple methods and their entry templates. ZURB also has plenty of support on GitHub, with no fewer than 14,000 submissions and more than 940 contributors. The framework is currently used by well-known websites such as the Washington Post and National Geographic.

4. UI Kit

UI Kit is known for having lightweight elements that are highly customizable. Its various templates allow you to easily build various Web interfaces. The UI Kit installation package contains packages for CSS, HTML and JavaScript files, and Sublime Text and Atom editors. In addition, it offers more than 30 modular components that users can mix and match to achieve a variety of functions. That is, you don’t have to search repeatedly for tags and class names.

Unlike other frameworks such as Bootstrap and Foundation, UI Kit doesn’t use a 12-column grid setup. Instead, it divides its layout into elastic, grid, and width sections. Of course, due to the lack of resources, the framework is more suitable for developers with more experience.

5. Bulma

As one of the most commonly used frameworks, Bulma is supported by more than 150,000 developers. It is one of the free open source frameworks based on Flexbox. Because the Bulma framework only fully meets the minimum requirements for developing responsive web sites, it is very easy for beginners to get started. In addition, Bulma has good technical support, thanks to a large community of users on GitHub.

6. Materialize

The front-end CSS framework was created according to Google’s design specification. Materialize comes with an easy-to-use grid of IZ columns for good layout design. Its package includes buttons, cards, tables, ICONS, and many other on-demand components. Other features you might use include drag-and-drop move menus, ripple effects animation, and SASS Mixins. Moreover, Materialize can be used on any type of device.

7. Semantic UI

Because it’s a relatively new framework, Semantic UI uses natural language in its code and is popular with beginners. Its Inheritance system comes with an advanced theme variable that gives you complete freedom at design time.

Because of the large number of third-party software libraries that come with the Semantic UI, you don’t have to call other libraries, making the Web development process much easier. This is why many beginners and experienced developers like it.

8. Tailwind CSS

Tailwind CSS differs from other frameworks in that its software package does not have pre-built UI components. The framework is more focused on practicality. It contains various CSS classes that focus on color, size, and location. Tailwind is for developers who are not satisfied with preset components, but want complete freedom to customize their Web designs.

9. Picnic CSS

The framework is very lightweight, with less than 10KB of compressed code. Picnic CSS also comes with a Flexx-based grid layout and many UI elements. You can use them to launch your own Web development projects. Picnic’s mode window and navigation bar are also very beginner friendly.

10. Ionic

The open source mobile UI framework allows users to develop native Android and iOS applications with high web performance without changing the code base. Ionic comes with intuitive UI components that help users speed up the development process for websites or applications. With its superior native functionality and speed, Ionic works well with communities, mainstream analytics platforms, authentication services, plug-ins, and other integration platforms.

11. Pure.css

The framework focuses on the idea of mobile first. Because pure.css is modular, you can easily import element packages on demand. You can also get its various downloadable and installable layouts. The pure.CSS framework, known for its lightness, is only 3.8KB compressed.

12. mini.css

Mini-css also offers comprehensive functionality and a lightweight framework. Although it is only 10KB compressed, it still provides rich layout and UI elements. If you want to learn more about how it works, check out its online documentation.

13. Base

If your primary mission is to lay a solid foundation for all your application and Web development projects, you should give this modular framework a try. Billed as a “rock-solid” response framework, Base provides basic customizable styles based on normalize.css. You can use it to implement simple applications on demand.

14. Concise CSS

CSS is also a simple and useful framework. The framework is compact, crisp, and requires no extra work. Of course, if you need UI elements, you can easily append them through a separate toolkit.

15. Mobi.css

At just 2.6KB in compression, mobi.css is one of the smallest frameworks you can find today. Mobi’s strength is speed, especially in mobile application scenarios. Because mobi.css has a built-in theme and plug-in system and can be extended on demand, users can take a modular approach and build on top of it.
