Is it possible to override Bootstrap or not?

Question

Is it possible to override Bootstrap or not?

It's quite a puzzle to figure out when I can and cannot override Bootstrap classes or IDs with custom CSS.

For instance, it seems easy enough to change the default navbar-dark background and font style, but altering the font color and size proves to be more challenging without resorting to inline styles or an external CSS file linked to an ID.

Here's what doesn't work:

<nav class="navbar navbar-dark"style="background: red; color: 
yellow; font-family: cursive font-size: 50px;">
  <a href="" class="navbar-brand" style="color: yellow; font-size: 
 50px;">PATTERN</a>
</nav

However, applying style directly to elements does work, like so:

<nav class="navbar navbar-dark"style="background: red; font-family: 
cursive;">
  <a href="" class="navbar-brand" style="color: yellow; font-size: 
 50px;">PATTERN</a>
</nav

The reliance on using IDs within each element becomes problematic when dealing with a large navbar that requires a uniform class to be applied.

How can I better understand these limitations and customize effectively?

Thanks! :)

The color style in Bootstrap can be set either on the parent element and then descend, or directly on the child element. In this case, it is set on the child element, so you will need to set it directly on that child.

It is recommended to use CSS, LESS, SASS, etc., instead of inline classes to apply styles globally to all children you want to target.

For example:

.navbar-dark .navbar-brand {
    color: yellow;
}

The issue you're encountering stems from CSS Specificity. When multiple CSS rules conflict for the same element, specificity comes into play. The specificity of CSS rules determines which rule will be applied to your HTML element. Generally, more specific rules override less specific ones. Here is the hierarchy of specificity:

Inline styles: styles defined in the "style" attribute within the HTML tag.
ID: a CSS rule that targets an element by its ID rather than a class (e.g., #navbar).
Classes, attributes, and pseudo-classes: common CSS rules like:

.blueBackgroundClass {
   background: blue;
}

Elements and pseudo-elements: typically used for generic site-wide styles, such as:

p {
   font-family: "Times New Roman", Times, serif;
}

a {
   color: blue;
}

To delve deeper into this topic, I highly recommend referring to the CSS Specificity documentation.
