What is the default orientation of flex container? vertical ? horizantal ? perpendicular? diagonal?
The Correct Answer and Explanation is:
The default orientation of a flex container is horizontal.
Correct Answer: Horizontal
Explanation
In CSS Flexbox (Flexible Box Layout), a flex container is created by applying display: flex or display: inline-flex to a parent element. The direction in which the flex items (children of the container) are laid out is determined by the flex-direction property.
By default, the flex-direction is set to row, which means the main axis is horizontal, and the flex items are arranged from left to right. This is the default behavior unless you explicitly change it using the flex-direction property.
Here’s how the default setting works:
cssCopyEdit.container {
display: flex; /* default flex-direction is 'row' */
}
With the above CSS, all direct children (flex items) of .container will be laid out in a horizontal line from left to right, just like words in a sentence. This behavior matches the natural left-to-right reading order in most Western languages, which is one reason for the default horizontal orientation.
You can change the orientation using the flex-direction property:
row(default): Horizontal, left to right.row-reverse: Horizontal, right to left.column: Vertical, top to bottom.column-reverse: Vertical, bottom to top.
The terms perpendicular and diagonal are not valid options or orientations in Flexbox terminology. “Perpendicular” might describe the cross axis (opposite of the main axis), but it is not a layout direction by itself. “Diagonal” layout is not natively supported in Flexbox—it would require transformations or other layout techniques.
In summary, when you use display: flex, the default layout direction is horizontal (flex-direction: row), which places items side-by-side from left to right, unless specified otherwise.
