CSS Grid vs Flexbox Essentials Quiz Quiz

Test your understanding of CSS Grid and Flexbox layout systems with these key questions. This quiz focuses on fundamental differences, usage, and properties to help you master responsive web design with CSS.

1. Order Property Applicability

   Does the order property apply to both flex items and grid items in CSS?

   1. only to grid items
   2. false
   3. only to flex items
   4. true

   Explanation: The order property can be used to change the visual order of both flex items and grid items. Flexbox and Grid layouts both respect the order property, allowing you to rearrange elements without changing the source code. The options 'only to flex items' and 'only to grid items' are incorrect because both layout systems support this property. 'False' is wrong since the property is applicable to both.

2. Defining Equal Row Heights in Grid

   Which CSS property makes all rows in a CSS Grid container have equal height?

   1. grid-rows: 1fr;
   2. grid-template-rows: 1fr;
   3. grid-auto-rows: 1fr;
   4. grid-template-rows: repeat(auto-fill, 1fr);

   Explanation: The correct property is 'grid-auto-rows: 1fr;', which sets equal heights for automatically created rows in CSS Grid. 'grid-template-rows: 1fr;' only sets one template row of equal height, but doesn't affect auto-created rows. 'grid-rows: 1fr;' is not a valid property. 'grid-template-rows: repeat(auto-fill, 1fr);' would create multiple rows, but auto-fill works differently and may not always result in equal heights for all rows.

3. Setting Columns in Flexbox

   How can you define three columns of equal width using Flexbox in CSS?

   1. column: repeat(3, auto):
   2. flex-basis: 33%;
   3. flex-column: 3;
   4. We cannot do this

   Explanation: You can achieve three equal-width columns in Flexbox by setting 'flex-basis: 33%' on each item, dividing the container space equally. 'flex-column: 3;' and 'column: repeat(3, auto):' are invalid CSS properties and do not define columns. 'We cannot do this' is incorrect because such layout is achievable with Flexbox using the correct property.

4. Aligning Items Along the Main Axis in Flexbox

   Which property would you use to distribute flex items evenly along the main axis with space between all items including edges?

   1. space-evenly
   2. space-between
   3. space-around
   4. space-equally

   Explanation: 'space-evenly' is used with the justify-content property and distributes items so that the space between any two items and edges is equal. 'space-between' only adds space between items and not at the edges. 'space-around' adds half-space at the edges, making item spaces unequal. 'space-equally' is not a valid CSS value.

5. Grid Area Shorthand Syntax

   What does 'grid-area: 1/4;' specify for a grid item in CSS Grid layout?

   1. grid-row-start: 1; grid-row-end: 4;
   2. grid-row-start: 1; grid-column-start: 4;
   3. it's invalid
   4. grid-column-start: 1; grid-column-end: 4;

   Explanation: 'grid-area: 1/4;' is equivalent to setting the starting row to 1 and starting column to 4 for a grid item. 'grid-column-start: 1; grid-column-end: 4;' is incorrect because it sets different tracks. 'grid-row-start: 1; grid-row-end: 4;' defines a row span, not a simple placement. The statement 'it's invalid' is incorrect, as this is a valid shorthand.
