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.

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.
