SwitchClass or AppendClass are not compatible with input tags

I am having trouble changing the border color of an input element using jQuery. Here is the setup:

<input id="box" type="text" />

And the CSS class I am trying to toggle:

.box-change
{
    border-color:#ffffff;
}

Below is the jQuery code I am using:

$('#box').toggleClass('box-change');

However, despite applying the class, the border color does not change as expected. Can anyone help me understand why this is happening?

Edit:

In addition to the class, the input element already has certain styles applied to it:

#box
{
border-color:#ff0000;
border-style:solid;
border-bottom-width:1px;
border-left-width:1px;
border-top-width:1px;
}

Answer №1

If you initially removed the border, you will need to specify

border-width

and

border-style

So basically your CSS should be like this:

.box-change
{
    border: 1px solid #fff;
}

However, the effectiveness of this depends on various factors such as the initial style, background color of the container element of your input, etc...

Make Adjustments after Providing More Details

Your class may not be applied because a class that sets style by ID takes precedence in the cascade over a CSS class. This is likely why you are not seeing the changes.

If you want your CSS class to have priority, you have two options:

  1. Use !important:

    .box-change
    {
        border: 1px solid #fff !important;
    }
    
  2. Create a CSS rule with higher specificity:

    #box.box-change
    {
        border: 1px solid #fff;
    }
    

The second method is preferable as using !important can make your CSS harder to manage and control. Reserve it for rare situations.

Troubleshooting Tips

For future reference, utilize browser developer tools (such as Chrome DevTools or Firebug) to identify issues quickly. Also, familiarize yourself with CSS specificity rules and how they impact cascading styles.

Answer №2

When your original styles are set with #box, they tend to be more specific than .box-change, causing them to override any new additions you make. Another possibility is that .box-change may have a higher priority in the cascade compared to #box.

To resolve this issue, you have two options:

#box.box-change{
  border-color: #fff;
}

or

.box-change{
  border-color: #fff !important;
}
