Tailwind CSS: Learn the joys of functional, responsive CSS

Maria J. Danford

Tailwind CSS is a newer CSS framework initial released in late 2017. It requires a unique approach to styling that may possibly shock you. In individual, Tailwind abandons semantic class names in favor of the far more objective-oriented courses observed in “functional CSS.”

Practical CSS vs. semantic CSS

To get a feeling of the difference, take into account a header component. Let us say we want to make it bold and red. In semantic CSS, we are encouraged to produce a class that describes the position the class performs in our application, say application-header, and then implement the essential designs: application-header: font-pounds: bold coloration: red . The idea listed here is that you are creating courses that are meaningful to you with regard to their semantic (as opposed to syntactic) position in the UI style.

On the other hand, in useful CSS, you would produce a class that describes the action of the type, this kind of as textual content-bold-red. Tailwind requires this method and creates a wealth of utility courses for use throughout your apps. For case in point, in Tailwind you’d use font-bold and textual content-red to produce your header type.

This flies in the facial area of regular wisdom when creating stylesheets. But sometimes regular wisdom is incomplete, and it turns out that Tailwind’s approach can make for a powerful—and simple—approach to styling the UI. Tailwind uses a dependable naming convention, and as a final result you can commence (much more quickly than with CSS or a further framework bootstrap) to retain all of its abilities in your head, so you can type your software with no breaking stride.

For case in point, in Tailwind the shorthand for padding is p-, where the initial letter indicates padding, and the 2nd the value of that padding. So p- sets the padding to , the equal of padding 0px 0px 0p 0px in a type. Also, you can set the left padding to zero with pl-, the left and ideal to zero with px-, and major and base to zero with py-. Which is fairly handy.

In this tutorial, you will see how to construct a responsive structure to get a deeper knowledge of how Tailwind CSS works.

Such as Tailwind

Start off by creating a new folder to maintain the tutorial challenge, and produce an index.html file. The fastest way to consist of Tailwind in your file, by using unpkg, is seen in Listing 1. Add this header to your file.

  Intro to Tailwind CSS

Tailwind navbar case in point

Let us commence with a navigation bar. Listing 2 has a easy navbar with a title, a couple of hyperlinks, and a history coloration.

Listing 2. A easy navbar


Listing 2 specifies a flex structure with the flex Tailwind class. It also specifies the justify-content material: place-in between type with justify-in between and justify-items: middle with items-middle. You can commence to see how Tailwind’s utility courses present a form of shorthand for designs.

Following, Listing 2 uses the h-28 utility to give the navbar a set top of 7rem. The heights and widths in Tailwind are ordinal numbers that are related with rem values (far more details on top utilities listed here).

The history of the navbar is set with bg-blue-four hundred. Tailwind hues stick to a residence-coloration-intensity format in this situation history, blue, and four hundred.

Finally, a padding of left and ideal twenty is set with the syntax you have currently seen: px-twenty.

Responsive layouts in Tailwind

Now you will see how to make things responsive. For the navbar, we want to middle almost everything and hide the hyperlinks and substitute them with a cell toolbar icon that opens a menu. (We’ll use a splash of vanilla JavaScript to attain the display/hide.)

Tailwind contains built-in breakpoints for dealing with responsiveness. These are shown in Desk 1. It is also probable to configure custom breakpoints.

Desk 1. Default responsive breakpoints

The idea listed here is you use the breakpoint title as a prefix to figure out if the prefixed class will implement, like so: breakpoint:class. A important place to know about Tailwind is that it is cell initial, so default courses will implement to almost everything. Breakpoints then manage what applies heading up in size from there. Return now to the navbar to get a concrete knowledge of this idea.

Responsive navbar case in point

Modify the index.html to glimpse like Listing 3.

Listing 3. The responsive navbar

Discover we have added the flex-col and md:flex-row courses to the navbar itself. This suggests that on products of 768px or higher the flex structure will be row. This is the usual sample of defining default cell designs and then overriding them on greater screens. We also enable the default top for the bar and then override it on medium-size and greater screens with md:h-28.

We use related methods to arrange the ul aspects.

Discover too that we hide the cell button (described as an inline SVG) for medium dimensions with mh:hidden. The button will for that reason appear as we want for lesser screens.

The JavaScript employed to display/hide the menu in cell is seen in Listing 4. Note how it just uses the Tailwind hidden class. This script goes at the finish of the HTML entire body.

Listing 4. Clearly show/hide JavaScript

Column layouts in Tailwind

Now transform your attention to the webpage entire body. A prevalent responsive structure is to have a grid of cards that will be just one, two, or three columns dependent on the display screen size. We are heading to produce that future with Tailwind.

To start with, make a couple of easy card divs, as in Listing five. These cards have a width, top, and rounded border, applying syntax you have seen.

Listing five. Straightforward card


Card 1

Card 2

Card 3

Card 4

Card five

Card six



Following, let’s make the card container a responsive grid, applying the courses seen in Listing six.

Listing six. Responsive grid container

Tailwind can make it pretty easy to change the grid columns centered on breakpoints. You can see how the default structure will comprise a solitary column, and then step by step far more columns will be added for greater dimensions. You can view this in your browser, resize the display screen, and enjoy the structure change.

Now let’s make improvements to the styling for the cards. Listing 7 has a sample of a card with a title.

Listing 7. Card styling

Title 1

Lorem ipsum dolor sit amet, consectetur adipiscing elit


Listing 7 can make use of lots of Tailwind shortcuts to increase rounded borders and a bolded, colored title bar. Also detect that the card is now applying md:w-eleven/12. This syntax for width can make for a proportional width of eleven/12ths (or the equal of width: ninety one.666667%).

Tailwind cheat sheet

Tailwind packs a good deal of electricity into a memorable and concise syntax. A terrific useful resource is this Tailwind CSS Cheat Sheet, which is handy for quickly wanting up what you want.

Tailwind is an choice to approaches like Bootstrap or Basis. It would seem to be catching on, thanks to its higher simplicity. In addition, Tailwind tops the charts for developer interest and pleasure.
