After donwloading mini.css, pick a Flavor and use it for your project.

Alternatively, you can use either GitCDN or RawGit to import the default flavor of mini.css. Simply add one of the following references inside your HTML page's <head> tag:

<link rel="stylesheet" href="">
<link rel="stylesheet" href="">

Finally, you can find mini.css on cdnjs, which you can use to include it in your projects.

Quick overview

Take a couple of minutes to learn how mini.css differs from all those other UI frameworks (Bootstrap, Semantic UI etc):

Framework file size comparison
NameVersionSize (uncompressed)Size (minified)Size (gzipped)
Bootstrap v3.3.7 143 KB117 KB20 KB
Material Framework v3.0 114 KB90 KB18 KB
mini.css v2.1.2 50 KB40 KB7 KB
Semantic UI v2.2.10 752 KB553 KB95 KB
Zurb Foundation v6.3.1 103 KB73 KB13 KB

 The above comparison takes into account only the CSS files of each framework. mini.css's size is an approximation due to the nature of its flavor system. The calculated results were produced using Refresh-SF.

Why does mini.css have so few modules?

Modules are what make frameworks so powerful, by giving developers the essential components they need to structure and style their websites. mini.css simplifies the crafting and learning process for new developers by providing a handful of very powerful modules that can do many different things. This way, new developers will only have to learn a few different HTML structures and patterns, while having the ability to build a lot of interesting things with them. For example, cards can be used for almost any type of layout and can be customized to behave exactly as the developer needs them to. Tabs, on the other hand, are very responsive on mobile, collapsing to a stack below a certain width, but they can also be forced into a stack, allowing accordions and collapses to be built using the same building block as tabs.

Browser support
BrowserNot supportedPartially supportedFully supported
 Internet Explorer 8-9-1011+
 Edge n/an/a12+
 Firefox 21-22-2728+
 Chrome 20-n/a21+
 Safari 6-n/a6.1+
 Opera 11.5-12.1-1617+
 Android Browser 4.3-n/a4.4+

 Due to the way mini.css is crafted, some legacy browsers are not supported anymore and some others are partially supported. This could be a dealbreaker for some developers, however most legacy browsers will display a less feature-rich and modern website. Apart from the table above, note that some mobile browsers like Opera Mini, IE Mobile and UC Browser for Android are officially supported, but some features may not be displayed properly or behave as expected due to the browsers themselves.
