This tutorial discusses the concepts behind achieving typewriter effect with CSS, with no Javascript involved.


Twinkle, twinkle, little star.

Using a Monospace Font

A monospace font contains letters and characters of equal width. This is different from conventional fonts in which characters are of different width.

To achieve a typewriter effect, it is important to use a monospace font. A monospace font, along with a valid animation-timing-function, will ensure that only a single character comes up in each step of the animation.

Some examples of monospace fonts are Courier, Consolas, Roboto Mono etc

CSS Properties Being Animated

In achieving a typewriter effect, basically the width CSS property is being animated from 0% to 100%.

The cursor at the end is basically a border on the right side. The blinking effect is achieved by infinitely animating the border-color property, from a solid color to transparent.

Performing Animation in a Fixed Number of steps

The main hero of this animation is the animation-timing-function property. To look like a realistic typing effect, we want the animation to push out a single character at a time. We don't want the animation as a smooth movement from one state to another, because then it won't look realistic. (You can try it yourself by editing the below codes).

Setting animation-timing-function as steps makes sure that the animation is performed in a series of steps. In short you can specify the number of "frames" in the animation.

In case of the text "Twinkle, twinkle, little star." - which contains 30 characters, the value becomes steps(30, end). The second parameter "end" specifies the movement to stay at the end till the duration of the step is over.
