Removing input background colour for Chrome autocomplete?

The previous solutions of adding a box-shadow works well for people who need a solid colour background. The other solution of adding a transition works, but having to set a duration/delay will mean that at some point it may show again.

My solution is to use keyframes instead, that way it will always show the colours of your choosing.

@-webkit-keyframes autofill {
    0%,100% {
        color: #666;
        background: transparent;
    }
}

input:-webkit-autofill {
    -webkit-animation-delay: 1s; /* Safari support - any positive time runs instantly */
    -webkit-animation-name: autofill;
    -webkit-animation-fill-mode: both;
}

To have a transparent background while not using a time delay (especially needed in modern web applications where people can stop using it for a while and want a predictable behavior of the interface), use this:

input:-webkit-autofill { 
    -webkit-background-clip: text;
}

body {
  background: lightblue;
}

input {
  background: transparent;
}

input.no-autofill-bkg:-webkit-autofill {
  -webkit-background-clip: text;
}

<input type="text" name="email" />
<input type="text" name="email" class="no-autofill-bkg" />

Working on: Chrome 83 / 84.0.4147.89, Edge 84.0.522.44

If you decide to re-post my solution, I only ask that you include my name or link to this.

You can change input box styles as well as text styles inside input box:

Here you can use any color e.g. white, #DDD, rgba(102, 163, 177, 0.45).

But transparent won't work here.

/* Change the white to any color */
input:-webkit-autofill,
input:-webkit-autofill:hover, 
input:-webkit-autofill:focus, 
input:-webkit-autofill:active{
    -webkit-box-shadow: 0 0 0 30px white inset !important;
}

Additionally, you can use this to change the text color:

/*Change text in autofill textbox*/
input:-webkit-autofill{
    -webkit-text-fill-color: yellow !important;
}

Advice: Don't use an excessive blur radius in the hundreds or thousands. This has no benefit and might put processor load on weaker mobile devices. (Also true for actual, outside shadows). For a normal input box of 20px height, 30px ‘blur radius’ will perfectly cover it.

I have a better solution.

Setting the background to another color like below didn't solve the problem for me because I needed a transparent input field

-webkit-box-shadow: 0 0 0px 1000px white inset;

So I tried some other things and I came up with this:

input:-webkit-autofill,
input:-webkit-autofill:hover,
input:-webkit-autofill:focus,
input:-webkit-autofill:active {
    transition: background-color 5000s ease-in-out 0s;
}
