How to increase text input width (with transition) when it is hovered in Tailwindcss

Question

I was able to change the width of a text when it is hovered after adding hover in tailwind.config.js

width: ['responsive', 'hover', 'focus'],
.
.
.
transitionProperty: ['responsive', 'hover', 'focus'],
transitionTimingFunction: ['responsive', 'hover', 'focus'],
transitionDuration: ['responsive', 'hover', 'focus'],
transitionDelay: ['responsive', 'hover', 'focus'],

However the animation effect is ugly and I wanted to add some transition but it doesn't seem to work. Here is the HTML part:

<input type="text" placeholder="Search" class="placeholder-gray-500 rounded-full px-3 pl-8 py-1 outline-none transition duration-700 ease-in-out focus:shadow-outline hover:w-64" />

Sample fiddle: https://jsfiddle.net/codename2200/30wjcndm/9/

Since there is no tailwind config in jsfiddle I just extracted the styles (with purge) to replicate what I've got so far.

Answer 1

Transition of size (height, width) will not work with "auto" value. You did not set any width on this input so it is auto be default. So if you have hover:w-64 then you need to set for ex. w-56.

Second issue with your code is transition class. By default it covers transitons of: background-color, border-color, color, fill, stroke, opacity, box-shadow, transform Check docs. Like you see there is no "width". So you can change it in tailwind config or just use transition-all instead.
