Utilize jQuery to alter the global CSS declaration

I have been utilizing Twitter Bootstrap to generate form components as illustrated below. Typically, the 'submit' button should be placed outside of the 'controls' container, however, for my specific layout requirements, I need it to be inside like so:

<div class="control-group">
    <div class="controls">
        <input type="text" name="email" value="" id="email" class="input-large email" placeholder="email" required="">  
        <input type="submit" value="submit" name="submit" id="submit" class="btn btn-success">
    </div>
</div>

Everything is functioning correctly except for one issue - when I apply the 'error' class to

<div class="control-group error">

, the styling also affects the 'submit' button which is not desired. To prevent this styling conflict, I can modify the bootstrap CSS to include :not([type='submit']) in the following manner:

.control-group.error input**:not([type='submit'])**, .control-group.error select, .control-group.error textarea {
border-color: #B94A48;
-webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
-moz-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}

AND 

.control-group.error .checkbox, .control-group.error .radio, .control-group.error input**:not([type='submit'])**, .control-group.error select, .control-group.error textarea {
color: #B94A48;
}

Nevertheless, I am contemplating whether there is an alternative method with jQuery to prevent this style from cascading down entirely if the element belongs to a specific type ...

Otherwise, I am considering

  1. finding a way to instruct a particular element to disregard a specific CSS class
  2. creating an exact replica with all CSS attributes applied to the element before adding the error class and then substituting it afterwards

Answer №1

In my usual practice, I include a custom class in the overall stylesheet to replace the error class on the particular field. This can be achieved by increasing specificity in your CSS. It's proven to be the most straightforward (though not necessarily the most correct) approach for ensuring full compatibility across various browsers.

Answer №2

To create a specific styling for your error message, consider enclosing it within a span element.

<div class="form-group">
  <div class="input-controls">
    <span class="error-message">
      <input type="text" name="username" value="" id="username" class="input-medium username" placeholder="Username" required="">  
    </span>
    <input type="submit" value="submit" name="submit" id="submit" class="btn btn-primary">
</div>

By nesting the error message within a span, you can isolate and style it as needed.
