Using the answer from Removing input background colour for Chrome autocomplete? I would like to disable the autofill background color but only on specific forms.
.myform input:-webkit-autofill,
.myform input:-webkit-autofill:focus {
    -webkit-transition: color 9999s ease-out, background-color 9999s ease-out;
    -webkit-transition-delay: 9999s;
}
Html:
<form class="myform" method="POST" action="targetpage.aspx">
    <input type="text" name="Username">
    <input type="password" name="Password">
</form>
But the above is not honored (e.g. in Chrome).
Adding .myform makes it fail.
Is there something obvious I'm missing?
