When using a mixin, you apply it to your styles with the ________ directive.
- @apply
- @extend
- @mixin
- @use
Mixins in SCSS are applied to your styles using the @include directive. This allows you to include the styles defined in the mixin within your CSS rules.
Which CSS property is used to vertically align inline elements or inline-block elements?
- margin
- padding
- text-align
- vertical-align
The CSS property used to vertically align inline elements or inline-block elements is vertical-align. It allows you to control how the element aligns in relation to the surrounding content or other inline elements.

In a list where you want to style only list items that are not the first child, you'd use the pseudo-class ________.
- :first-item
- :last-child

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.
You're working on a project where you need to ensure that your CSS code is compatible with the last two versions of all major browsers. Which tool would be best suited for this requirement?
- Autoprefixer
- CSS Lint
- SASS
- CSS Grid
For ensuring compatibility with the last two versions of major browsers, Autoprefixer is the ideal tool. It automatically adds vendor prefixes to your CSS code, ensuring that your styles work in various browsers. This is essential for maintaining cross-browser compatibility.
PostCSS allows developers to use tomorrow's CSS syntax by transforming it into ________.
- CSS
- JavaScript
- Machine Code
- SVG
PostCSS is a tool used to process CSS and extend it with new features. It allows developers to use future CSS syntax by transforming it into standard CSS. In this context, the answer is "CSS."
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.
The space between the content of an element and its border is determined by the ________ property.
- Border
- Margin
- Outline
- Padding
The space between the content of an element and its border is determined by the "padding" property in CSS. Padding provides the spacing between the content and the border of an element, allowing you to control the inner spacing.
To ensure that fonts are loaded from the same origin, you can use the ________ HTTP header.
- Access-Control-Allow-Origin
- Cache-Control
- Content-Disposition
- User-Agent
To ensure that fonts are loaded from the same origin, you can use the Access-Control-Allow-Origin HTTP header. This header specifies which origins are permitted to access a resource, which is useful for preventing cross-origin resource sharing issues.
You're creating a fluid typography system where the font size should never go below 16px, never exceed 32px, and scale smoothly between these values based on the viewport width. Which CSS function will help you achieve this?
- calc(16px + 3vw + 1vh - 32px)
- clamp(16px, (3vw + 1vh), 32px)
- fluid-size(16px, 32px)
- font-size: 16px; min-font-size: 32px; vw-font-scale: 3vw; vh-font-scale: 1vh;
To create a fluid typography system with specified limits and smooth scaling based on viewport width, you should use the clamp() function. The correct option is clamp(16px, (3vw + 1vh), 32px), which ensures the font size stays between 16px and 32px while smoothly scaling with viewport width changes.
