Question

What is the best way to add an element to multiple websites while avoiding the inheritance of their styles?

Is there a way to add a select element with my own styling to various websites? Many of them have heavily styled their existing select elements, which do not have any classes.

How can I ensure that my customized select does not inherit the styles from the specific website?

Based on the code snippet below, I anticipate that my_select will not be affected by the default select styling.

select {
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
 /* 50x more rules that i dont want to overwrite one by one */
}

<!-- Their select -->
<select>
    <option value="">Their select</option>
</select>

<!-- Mine select -->
<select class="my_select" id="my_select">
    <option value="">My select</option>
</select>

Perhaps this is the solution you've been seeking. By resetting all attributes to their initial values, you can start with a clean canvas to apply your own custom styles. It's worth noting that this approach may lead to unexpected outcomes since the initial values might not align with your expectations.

select {
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
  border: 1px solid red;
 /* Additional rules that I prefer not to override individually */
}

.my_select {
    all: initial;
    /* Define your unique styles here */
}

<!-- Their select -->
<select>
    <option value="">Their select</option>
</select>

<!-- My select -->
<select class="my_select" id="my_select">
    <option value="">My select</option>
</select>

Assign a distinct ID to your selection that is unlikely to match any existing on the external site:

From what I know, it seems impossible to achieve this in CSS alone. The key lies in specificity - if you only target an element tag, any styles applied will be overridden by the same tag with a class attached. To make your styles work, you need to enhance specificity in your CSS (using id, class, etc.), or as a last resort, utilize !important. Alternatively, setting up everything through JavaScript may also be an option.
