What is flexbox?

Flexbox is the one-dimensional layout model. Which helps to align elements in a row direction or column direction. It gives flexibility to the user interface for responsive web pages.

Display Flex

By default, the display property is a column direction when the flex is applied to the display and turns into a Row direction property.

example: default Without flexbox

General syntax

.parentContainer {
  display: flex; 
}

Items start from the right side of the web page.

.parentContainer {
 display: flex; 
Justify -content: flex-end;

Center

This is the most used property of the flexbox. This makes items to the center along the horizontal line. and for verticle, we used the align-items property.

.parentContainer {
 display: flex; 
Justify-content: center;
align-items: center;
}

Space-around, Space between, and space evenly

Space-around: Spreads space around the items with equal space but when items have their own space they took their space also.

.parentContainer {
 display: flex; 
Justify-content: space-around;

}

Space between: Spreads space between the items with equal space. the first item at the start and the last item at the end of the web page.

.parentContainer {
 display: flex; 
Justify-content: space-between;

}

Space evenly: Spreads space evenly for the items with equal space.

.parentContainer {
 display: flex; 
Justify-content: space-evenly;

}

Align Items

flex-start and flex-end

items are placed at the start of the cross-axis and with flex-end items are placed at the end of the cross-axis

.parentContainer {
 display: flex; 
align-items: flex-start;

}

.parentContainer {
 display: flex; 
align-items: flex-end;

}

Used for align-items vertically center, generally used with justify-content center.

.parentContainer {
 display: flex; 
Justify-content: center;

 display: flex; 
align-items: stretch;
}

Row gap and Column gap

Provides gap between rows and columns.

.parentContainer {
 display: flex; 
row-gap:30px;
column-gap:20px;
