![]() ![]() JIT mode ( Just-In-Time) is an alternative way to generate the CSS that, instead of generating all possible classes and then removing all those that are not being used, parses the content of HTML files (or configured extensions or locations) and instantly generates only those classes that are needed and used.īecause all possible variables are no longer generated, the waiting time and size of the resulting CSS files is greatly reduced. This mode of operation is no longer available in version 3 of Tailwind CSS. Then, by means of another utility such as PurgeCSS, all the files are traversed, and the classes that are not being used are removed from the resulting CSS file.ĭue to the number of classes that can be generated by the number of variants and their combinations, this method has the drawbacks of long waiting times and large sizes of CSS files before being purged. The default mode of Tailwind is that the system generates all possible CSS combinations based on the project settings. In the configuration one can set the values of the utility classes, such as the color-palette or the sizes between elements for margins. It is possible to configure the utility classes and variants that Tailwind offers through a configuration file usually named. Tailwind CSS is developed using JavaScript, runs via Node.js, and installs with environment package managers like npm or yarn. For example, the variant md:bg-yellow-400 will apply the class bg-yellow-400 if the screen size is greater than the value defined for md. Variants have two parts: the condition to be met and the class that is applied if the condition is met. There are also variants for the different states an element can have, such as hover : for when hovered, focus: when keyboard selected or active: when in use, or when the browser or operating system has dark mode enabled. The main use of variants is to design a responsive interface for various screen sizes. Tailwind offers the possibility to apply a utility class only in some situations through media queries, which is called a variant. Please be careful when feeding the birds. ![]() There are many utility classes in Tailwind CSS that enable to control a large number of CSS properties like colors, border, display type ( display), font size and font, layout, shadow. Each of these classes is called utility classes. ), classes are built around a specific style element (yellow color, bold font, very large text, center element.). Instead of creating classes around components (button, panel, menu, textbox. The utility-first concept refers to the main differentiating feature of Tailwind. Features ĭue to the difference in basic concepts in relation to other traditional CSS frameworks such as Bootstrap, it is important to know the philosophy from which Tailwind was created, as well as its basic usage. ![]() To achieve this result in Tailwind, one would have to apply a set of classes created by the library: bg-yellow-300 and font-bold.Īs of 30th July 2023, Tailwind CSS has over 70,000 stars on GitHub. įor example, in other traditional systems, there would be a class message-warning that would apply a yellow background color and bold text. Instead, it creates a list of "utility" CSS classes that can be used to style each element by mixing and matching. The main feature of this library is that, unlike other CSS frameworks like Bootstrap, it does not provide a series of predefined classes for elements such as buttons or tables. Tailwind CSS is an open source CSS framework. ![]()
