SCSS functions can be used to perform ________ before the CSS is compiled.
- Code execution
- Conditional statements
- Looping operations
- Mathematical calculations
SCSS functions can be used to perform mathematical calculations, such as addition, subtraction, and multiplication, before the CSS is compiled. This allows you to generate dynamic and responsive styles based on input values.
You are developing a website where you want to use modern CSS features not yet supported in all browsers. How can you ensure compatibility without manually writing fallbacks?
- Use a CSS preprocessor like SASS
- Employ a PostCSS plugin
- Write conditional JavaScript code
- Ignore unsupported features
To ensure compatibility with modern CSS features, you can use a PostCSS plugin like "autoprefixer" that automatically generates fallback code for unsupported features, allowing you to write modern CSS with confidence. This minimizes the need for manual fallbacks.
You are tasked with creating a list where every even item has a gray background. Which CSS selector would help you accomplish this?
- :even
- :nth-child(even)
- :nth-child(odd)
- :odd
To select every even item in a list, you should use the :nth-child(even) selector. This will apply the styling to the elements with even indices in the list, which will give them a gray background in this scenario.
What is the role of the grid-gap property in a grid layout?
- It defines the number of columns in the grid.
- It determines the background color of the grid.
- It sets the width of the entire grid.
- It specifies the gap between grid items.
The grid-gap property is used to specify the gap or spacing between grid items (rows and columns) in a grid layout. It helps in controlling the spacing and alignment of items within the grid.
What does the ::before pseudo-element do in CSS?
- It creates a pseudo-element that is the first child of the selected element, allowing content to be generated before the actual content of the element.
- It selects the element that comes after the targeted element.
- It selects the first child element of the parent element.
- It targets the element that is immediately before the current element.
The ::before pseudo-element in CSS is used to generate content before the content of an element. It creates an element that appears as the first child of the selected element and allows you to insert generated content (such as text or images) before the actual content of the element.
In CSS, if you want an element to inherit a property's value from its parent element, you would use the value ________.
- Copy
- Inherit
- Override
- Override-all
To make an element inherit a property's value from its parent element, you would use the 'inherit' value. This ensures that the child element inherits the property value from its parent.
Styled Components utilize ________ to generate unique class names for styles.
- BEM methodology
- Hashing algorithms
- Inline CSS
- Random strings
Styled Components generate unique class names for styles by using hashing algorithms. This ensures that styles are isolated and don't interfere with other components, a technique often referred to as "CSS-in-JS" or "CSS Modules."
What does the CSS property "line-height" primarily affect?
- Background color
- Font color
- Spacing between lines of text
- Text size
The CSS property "line-height" primarily affects the spacing between lines of text within an element. It determines the vertical distance between the baselines of two consecutive lines of text. Adjusting the line-height can impact the readability and aesthetics of text on a webpage.
The em unit in CSS is relative to the ________.
- Body background color
- Font-size of the parent element
- Screen width
- Width of the border
The em unit in CSS is relative to the font-size of the parent element. It's a relative unit, making it valuable for creating scalable and responsive designs. When you set an element's font-size in ems, it's relative to its parent's font-size.
How can you ensure that a CSS transition applies only when a specific property changes?
- By using the transition property without specifying any properties.
- By using the all value for the transition-property property.
- By creating a separate CSS class for each property you want to transition.
- By defining multiple transition rules for each property.
To ensure that a CSS transition applies only when a specific property changes, you can use the transition-property property and set it to "all." This means the transition will be applied to all properties that change. If you want to target specific properties, you can list them individually in the transition-property property. Using "all" is a convenient way to apply transitions to all changing properties.
