Is it possible to alter the background color once the content of an input field has been modified?

I am working with an angular reactive form and I want to dynamically change the background color of all input fields when their value is changed. Some of these input fields are pre-populated and not required. I came across a potential solution on Stack Overflow, but it seems to require my input fields to be marked as required:

<div class="form-group">
  <input type="text" class="form-control" required>
</div>
.form-control:valid {
  background-color:  #96d3ec!important;
}

I'm curious if the form-control class supports something like this:

.form-control:changed {
  background-color:  #96d3ec!important;
}

Answer №1

The answer that has been discovered does not necessitate the mandatory nature of your input fields ( as demonstrated in the second portion of the code solution ).

It is only the initial segment of the code solution that mandates a required field for validation purposes.
