Tailwind CSS: Learn the joys of functional, responsive CSS

Tailwind CSS is a newer CSS framework very first released in late 2017. It usually takes a distinct technique to styling that may surprise you. In individual, Tailwind abandons semantic course names in favor of the more function-oriented courses uncovered in “functional CSS.”

Useful CSS vs. semantic CSS

To get a perception of the distinction, consider a header element. Let’s say we want to make it bold and purple. In semantic CSS, we are inspired to develop a course that describes the part the course performs in our application, say application-header, and then apply the needed designs: application-header: font-fat: bold colour: purple . The notion below is that you are building courses that are meaningful to you with regard to their semantic (as opposed to syntactic) part in the UI structure.

On the other hand, in functional CSS, you would develop a course that describes the motion of the fashion, such as text-bold-purple. Tailwind usually takes this manner and makes a prosperity of utility courses for use across your programs. For case in point, in Tailwind you’d use font-bold and text-purple to develop your header fashion.

This flies in the face of traditional knowledge when building stylesheets. But in some cases traditional knowledge is incomplete, and it turns out that Tailwind’s technique makes for a powerful—and simple—approach to styling the UI. Tailwind employs a steady naming conference, and as a outcome you can start (significantly faster than with CSS or a further framework bootstrap) to retain all of its capabilities in your head, so you can fashion your application without breaking stride.

For case in point, in Tailwind the shorthand for padding is p-, where the very first letter implies padding, and the next the price of that padding. So p- sets the padding to , the equal of padding 0px 0px 0p 0px in a fashion. Moreover, you can established the left padding to zero with pl-, the left and appropriate to zero with px-, and best and base to zero with py-. Which is really helpful.

In this tutorial, you will see how to develop a responsive layout to get a deeper understanding of how Tailwind CSS will work.

Like Tailwind

Start out by building a new folder to hold the tutorial undertaking, and develop an index.html file. The quickest way to include things like Tailwind in your file, through unpkg, is witnessed in Listing 1. Increase this header to your file.

  Intro to Tailwind CSS

Tailwind navbar case in point

Let’s start with a navigation bar. Listing two has a uncomplicated navbar with a title, a handful of inbound links, and a background colour.

Listing two. A uncomplicated navbar


Listing two specifies a flex layout with the flex Tailwind course. It also specifies the justify-articles: space-amongst fashion with justify-amongst and justify-goods: centre with goods-centre. You can start to see how Tailwind’s utility courses give a kind of shorthand for designs.

Subsequent, Listing two employs the h-28 utility to give the navbar a fastened height of 7rem. The heights and widths in Tailwind are ordinal figures that are involved with rem values (more info on height utilities below).

The background of the navbar is established with bg-blue-four hundred. Tailwind colors adhere to a home-colour-depth format in this situation background, blue, and four hundred.

Eventually, a padding of left and appropriate 20 is established with the syntax you’ve already witnessed: px-20.

Responsive layouts in Tailwind

Now you will see how to make things responsive. For the navbar, we want to centre all the things and disguise the inbound links and substitute them with a cell toolbar icon that opens a menu. (We’ll use a splash of vanilla JavaScript to accomplish the show/disguise.)

Tailwind involves constructed-in breakpoints for dealing with responsiveness. These are revealed in Table 1. It is also feasible to configure custom made breakpoints.

Table 1. Default responsive breakpoints

The notion below is you use the breakpoint identify as a prefix to determine if the prefixed course will apply, like so: breakpoint:course. A vital stage to know about Tailwind is that it is cell very first, so default courses will apply to all the things. Breakpoints then control what applies heading up in sizing from there. Return now to the navbar to get a concrete understanding of this notion.

Responsive navbar case in point

Modify the index.html to glance like Listing three.

Listing three. The responsive navbar

Observe we have additional the flex-col and md:flex-row courses to the navbar by itself. This suggests that on gadgets of 768px or greater the flex layout will be row. This is the usual pattern of defining default cell designs and then overriding them on more substantial screens. We also let the default height for the bar and then override it on medium-sizing and more substantial screens with md:h-28.

We use equivalent tips to set up the ul things.

Observe as well that we disguise the cell button (outlined as an inline SVG) for medium dimensions with mh:concealed. The button will hence appear as we want for lesser screens.

The JavaScript employed to show/disguise the menu in cell is witnessed in Listing four. Notice how it just employs the Tailwind concealed course. This script goes at the conclude of the HTML entire body.

Column layouts in Tailwind

Now switch your notice to the webpage entire body. A common responsive layout is to have a grid of playing cards that will be just one, two, or three columns depending on the monitor sizing. We are heading to develop that following with Tailwind.

Very first, make a handful of uncomplicated card divs, as in Listing 5. These playing cards have a width, height, and rounded border, utilizing syntax you’ve witnessed.

Listing 5. Basic card


Card 1

Card two

Card three

Card four

Card 5

Card 6



Subsequent, let us make the card container a responsive grid, utilizing the courses witnessed in Listing 6.

Listing 6. Responsive grid container

Tailwind makes it incredibly uncomplicated to transform the grid columns based on breakpoints. You can see how the default layout will incorporate a one column, and then gradually more columns will be additional for more substantial dimensions. You can see this in your browser, resize the monitor, and watch the layout transform.

Now let us make improvements to the styling for the playing cards. Listing seven has a sample of a card with a title.

Listing seven. Card styling

Title 1

Lorem ipsum dolor sit amet, consectetur adipiscing elit


Listing seven makes use of numerous Tailwind shortcuts to incorporate rounded borders and a bolded, coloured title bar. Also recognize that the card is now utilizing md:w-11/12. This syntax for width makes for a proportional width of 11/12ths (or the equal of width: ninety one.666667%).
