When the value in a required input field is empty, the border is activated and the color is styled

Can you please explain this to me?

Try running this code in Firefox: http://jsfiddle.net/eMa8y/24/

Here is the HTML:

<html>

    <head>
        <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
    </head>

    <body>
        <form>
            <input type="text" placeholder="input" required />
            <input type="text" placeholder="input" />
        </form>
    </body>

</html>

CSS:

input {
    color:black;
}
[required] {
    color:red;
}

SCRIPT:

$(document).ready(function () {
    setTimeout(function () {
        $("input").val("");
    }, 3000);
});

If you wait three seconds, the input field will get a red border. Do you think this issue is specific to Firefox? Is it a bug?

Just wanted to mention that I am using Firefox version 18.0.2.

Thank you!

Answer №1

In Firefox, the HTML5 attribute required is displaying a red border. Here's a solution to remove it:

Firefox 4 Required input form RED border/outline

To fix this, simply add the following code:

[required] {
    color:red;
    box-shadow: none;
}

This should resolve the issue.

Answer №2

Firefox utilizes a specific style to highlight the need for input values, which is not considered a bug.

If you want more information on how Firefox supports the required attribute, check out this link: https://developer.mozilla.org/en-US/docs/HTML/Element/input#attr-required

For further clarification, visit:

The validation process in Firefox can cause your required input to lose focus due to the script looping through all inputs in the DOM. When there's an input behind it, Firefox will trigger validation to ensure that input has a value.

Below is the internal Firefox styling for invalid inputs:

:-moz-ui-invalid:not(output) {
    box-shadow: 0 0 1.5px 1px red;
}
