How do CSS preprocessors handle mathematical operations differently from regular CSS?
- They do not support mathematical operations
- They require the use of JavaScript for calculations
- They support mathematical operations directly

How does the concept of 'partials' in SASS help in managing large stylesheets?
- Applying global styles
- Creating small, modular style files
- Importing reusable pieces of code
- Organizing comments within stylesheets
In SASS, partials allow the creation of small, modular style files that can be imported into other stylesheets, promoting code organization and reusability. This helps manage large stylesheets by breaking them into manageable pieces.
How do you apply a bold style to text in CSS?

A web developer is implementing a theme switcher for their website using CSS variables. They need to ensure that the colors and font sizes adjust according to the user's preferences. What should they consider when implementing this feature?
- Applying JavaScript to handle theme switching for better control over dynamic changes.
- Ensuring proper usage of media queries to handle different user preferences.
- Using fixed units for colors and font sizes to maintain consistency across all devices.

When implementing a theme switcher with CSS variables, it's crucial to use CSS custom properties (variables) for defining colors and font sizes. This ensures flexibility and ease of maintenance. Proper fallbacks should be provided for browsers that don't support CSS variables.
In CSS, the ________ property can be used to specify the number of columns in a multi-column layout.
- column-count
- column-number
- column-layout
- column-span
The correct option is column-count. This property defines the number of columns an element should be divided into for a multi-column layout. It specifies the desired number of columns, and the content will automatically flow into these columns.
To override a CSS Variable in a specific context, you must define it within a ________ selector to increase its specificity.
- class
- specific
- media
- nested
The correct option is class. To override a CSS variable in a specific context, you should define it within a class selector. This increases the specificity of the selector, ensuring that the variable is applied within that specific scope, overriding any global variable with the same name.
A developer is tasked with creating a navigation menu where each list item has a custom icon instead of the default marker. How can they achieve this using CSS properties related to list styles?
- list-style-type: none; background-image: url('icon.png'); background-size: 20px 20px; background-repeat: no-repeat; padding-left: 30px;
- list-style-type: none; content: url('icon.png'); padding-left: 30px;
- list-style: none; background-image: url('icon.png'); background-size: 20px 20px; background-repeat: no-repeat; padding-left: 30px;
- list-style-type: none; background: url('icon.png') no-repeat left center; padding-left: 30px;
Option 4 is correct. It sets list-style-type to none and uses a background image for the custom icon, adjusting padding for spacing.
