What's the primary difference between the clip-path and mask properties in CSS?
- Clip-path works on images, while the mask property only works on text elements.
- The clip-path property can be animated, while the mask property cannot.
- The clip-path property clips an element to a specified shape, while the mask property applies an image as a mask to an element.
- The clip-path property is used for simple shapes, while the mask property is used for complex shapes.
The primary difference between clip-path and mask in CSS is that clip-path clips an element to a specified shape, whereas the mask property applies an image as a mask to an element. This fundamental distinction affects how elements are visually modified and displayed.
You need to create a layout where a sidebar stays to the left and the main content takes up the remaining width. Which combination of float and width properties would achieve this?
- Don't use float, set the main content's width to 100%.
- Don't use float, set the main content's width to a fixed value.
- Float the sidebar left and set the main content's width to 100%.
- Float the sidebar left and set the main content's width to a fixed value.
To create a layout where a sidebar stays to the left and the main content takes up the remaining width, you would float the sidebar to the left and set the main content's width to 100%. This ensures that the sidebar stays to the left while the main content occupies the remaining available space.
Which property in CSS determines the space outside an element?
- Border
- Content
- Margin
- Padding
In CSS, the 'margin' property is used to determine the space outside an element. It creates spacing around the element, separating it from other elements in the layout.
When an element's property is set to initial, it will use the ________.
- Current value
- Default value
- Inherited value
- Parent element's value
Setting an element's property to 'initial' means it will use the default value for that property as defined by the CSS specification. This effectively resets the property to its default state.
Which of the following properties, when animated, would cause a "repaint" but not "reflow" in most browsers?
- color
- margin
- position
- width
When animated, changing the color property of an element typically causes a "repaint" (updating the pixels on the screen) but not a "reflow" (changing the layout of elements on the page). This is because changing the color doesn't affect the size or position of the element, but it does require repainting.
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. It's commonly used for aligning elements such as images and text within a line of text.
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
- :not(:first-child)
- :not-first
To style list items that are not the first child, you can use the pseudo-class ":not(:first-child)." This allows you to target and style all list items except the first one in a list.
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.
