- column-count: 3; column-width: auto;
- columns: 3 auto;
- flex: 1 0 33%;
- grid-template-columns: repeat(3, 1fr);
To achieve a responsive multi-column layout, using the grid-template-columns property with repeat ensures three columns on wide screens while maintaining a single column on small devices.

For accessibility, using ________ in CSS can provide better control over how elements are read by screen readers.
- accessibility-control:
- aria-label:
- role:
- sr-only:
To enhance accessibility, using sr-only in CSS is beneficial. It helps provide better control over how elements are read by screen readers by visually hiding elements while keeping them accessible. aria-label and role are attributes used in HTML for accessibility, not CSS properties. accessibility-control is not a valid CSS property.
CSS Houdini is primarily aimed at allowing developers to do what?
- Automate the generation of HTML structure
- Extend and enhance the capabilities of the CSS engine

CSS Houdini is designed to extend and enhance the capabilities of the CSS engine, allowing developers to have more control and flexibility in styling web elements.
When using position: sticky;, which two properties must be set for the sticky behavior to work effectively?
- top
- left
- position
- display
The correct options for the position: sticky; to work effectively are position: sticky; and top. The position property must be set to sticky, and the top property should be defined to specify the position where the element becomes sticky.
You're designing a web application that requires certain elements to be draggable within the confines of a specific area. Which combination of positioning and other CSS properties will you need to consider?
- position: absolute, top: 0, left: 0; z-index: 1;
- position: fixed; width: 100%; height: 100%;
- position: relative; overflow: hidden;
- position: sticky, bottom: 0, right: 0;
To create draggable elements within a specific area, you should use position: relative on the container and set overflow: hidden. This allows the absolute-positioned elements to be confined within the container.
What distinguishes CSS Houdini's Animation Worklet from traditional CSS animations?

How would you create a transparent border that doesn't affect the layout dimensions of a box?
- border: 1px solid transparent;
- border: 1px transparent solid;
- border: transparent 1px solid;

In SASS, what is the difference between a mixin and a function?
- Functions return a single computed value, and they can be used in expressions.
- Mixins are blocks of reusable style declarations, and they don't return values.
- Mixins can accept parameters and include style rules, while functions perform computations and return a value.
- Mixins can only be used with @include, whereas functions are invoked with @function.
In SASS, mixins and functions serve different purposes. Mixins are used for reusable blocks of styles, often with parameters, while functions are designed to perform computations and return a single value. The key distinction lies in their usage and the nature of what they return. Understanding this helps in writing more modular and maintainable SASS code.
