How can you specify a fallback font if the primary font fails to load?
- Add the "secondary" attribute to the "font" property
- Define a secondary font using the "secondary-font" property
- Use the "fallback-font" property
- Utilize the "font-family" property with multiple font options
To specify a fallback font in case the primary font fails to load, you can use the "font-family" property with multiple font options.

If the primary font is unavailable, the browser will attempt to use the next font in the list until it finds a suitable option or defaults to a system font.

What is the difference between the em and rem units when setting font size in CSS?
- em and rem are identical; there's no difference between them.
- em is a fixed unit equivalent to 16px, while rem is relative to the parent element.
- em is a unit of measurement for page width, while rem is for font size.
- em is relative to the font-size of the element itself, while rem is relative to the font-size of the root element (html).
The em unit is relative to the font-size of the element itself, while the rem unit is relative to the font-size of the root element (html). This means that em units can compound if used within nested elements, whereas rem units remain consistent throughout. Understanding this difference is crucial for responsive design.

How does the SMACSS methodology recommend handling states, like "is-active" or "is-hidden"?
- Apply these states as classes in the HTML
- Avoid handling states in SMACSS
- Use JavaScript to toggle these states
- Utilize pseudo-elements like :active or :hidden
In the SMACSS (Scalable and Modular Architecture for CSS) methodology, states like "is-active" or "is-hidden" are typically handled by applying them as classes directly in the HTML markup. This allows for clear separation of styling and behavior, making the code more maintainable and modular.
