How do I change the border of a single input through CSS

[CD_Engineers]

Hello,

I’m trying to change the border of an input to red whenever there is an invalid value. I’m already changing the border to black using the SDK but how do I change a single input to red using CSS?

Sincerely,
Elijah

Hello,

You may assign a specific class to the input element for which you wish to change the border color, and apply similar CSS styles accordingly:

.bl-input.your-custom-class-name {
  fieldset {
    border-color: red !important;
  }
}

Regards,
Alexander
