How can CSS be applied to form elements in jQuery when the class attribute is already in use?

I have a question regarding form validation using Jquery. The form elements in my code have the class attribute set as "required".

Now, I want to style these input fields specifically without affecting all input elements. I have defined a CSS class like this:

Instead of a general CSS declaration for all input elements, I am using the following CSS rules:

input.form
{
    color: #000;
    background: #fff;
    border: 2px solid #E1E1E1;
    font-size: 16pt;    
    width:150px;
}

I would like to apply this styling by including the class attribute in the HTML like below:

However, this approach does not work due to having two class attributes present. Can anyone advise on how to handle this situation? Thank you.

Answer №1

Feel free to assign multiple classes to each element in your HTML code. An example of this would be:

<input class="form required" type="text" name="first_name" />

If you want to apply specific styling to input elements that have the "required" class, simply include the following CSS:

input.required
{
    border: 1px solid #000;
}

In HTML elements, each attribute can only be used once (it is believed that the last one will replace any previous ones). If you need to assign multiple classes, simply list them all within the same attribute separated by spaces:

<input type="text" class="form required invalid" name="element" id="element" />

To verify if an element has a specific class:

$('#element').hasClass('required');

To remove a class from an element:

$('#element').removeClass('invalid');

To add a new class to an element:

$('#element').addClass('valid');
