Answer 1

Answer №1

Due to the default styles of the h1 element, specifically the default font-size: 2em, it is necessary to explicitly set the font-size within the h1 styling.

Snippet

.pageStyle {
  font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;
  font-size: 18px;
}
h1 {
  font-size: inherit; /* or 18px */
}

Wouldn't the stylesheet override this default style?

The stylesheet will not override the default styles for the h1 element because the styles applied by the parent body are more specific than those directly applied to the h1.

Answer №2

The issue at hand relates to the concept of CSS specificity. According to information provided by Mozilla's documentation:

Selector types are ranked in terms of increasing specificity:

Type selectors (e.g., h1) and pseudo-elements (e.g., :before).

Class selectors (e.g., .example), attributes selectors (e.g. [type="radio"]) and pseudo-classes (e.g., :hover).

ID selectors (e.g., #example).

An important point to consider is the use of the !important declaration:

Whenever an important rule is applied to a style declaration, it takes precedence over any other declarations...

In the particular scenario described, default styles provided by the browser for all elements take precedence due to being defined based on the element's name (h1, a, etc.), which can lead to your custom styles not being implemented successfully. A visual representation showcasing default styles for h1 within the browser can be seen in this screenshot:

To resolve this, you could experiment with targeting h2 specifically or incorporating the pageStyle class onto h2 for desired outcomes.
