My typical approach involves simplifying and cleaning the design of the component:
- Assign a meaningful class name to the root element (such as
flyout).
- Use the root element's class name as a prefix for child element class names (e.g.
flyout-title, flyout-content, etc). In some cases, I may shorten the root element's class name (e.g. fly-).
<div class="flyout">
<div class="flyout-title">{{ title }}</div>
<div class="flyout-content"><slot/></div>
</div>
This is my personal naming convention, but consistency is key. Choose a naming convention that works for you and avoid conflicts with other class names throughout your application.
When using <flyout> as a child component that needs styling with CSS, provide it with a class name specific to the parent component. For instance, if the parent component is app-menu, name the flyout class app-menu-flyout. Consistency is key here as well.
<flyout class="app-menu-flyout"/>
In the <style> section of the parent component, define styles for the child component as follows:
.flyout.app-menu-flyout {
/* Styling for the root element */
}
.flyout.app-menu-flyout .flyout-content {
/* Styling for the child element */
}
I use selectors like this to ensure specificity and override any styles from the child component. This approach works regardless of the CSS order, which may vary depending on how it's bundled.
Keep in mind that this approach tightly couples the parent and child components in terms of template structure and class names. Any changes to the child component's template or class names will require corresponding updates in the CSS for all components styling it.
If you're using scoped CSS, be mindful of how child components should be styled.
