Advance CSS layout with flexbox
It is also called a flexible box model. It is basically a layout model that provides an easy and clean way to arrange items within container. Flexbox is different from the block model which is vertically bias and the inline which is horizontally bias. Flexbox was created for small-scales layouts and there’s another standard called grids which is geared more towards larger scale layouts, It works similar to the way to Twitter bootstrap grid system works. Flexbox is responsive and mobile-friendly. To start with flexbox firstly create a flex container. To create a flex container set the display property to flex.
Example:
.main-container {
display: flex;
}
Flex Properties:
- flex-direction
- flex-wrap
- flex-flow
- justify-content
- align-items
- align-content
flex-direction: The flex-direction is used to define the direction of flexible item. The default axis is horizontal in flexbox, so the items flow into a row.
Syntax:
// Stacking flex items column wise flex-direction: column; // Stacking flex items from bottom to top flex-direction: column-reverse; // Stacking flex items row wise flex-direction: row; // Stacking flex items from right to left flex-direction: row-reverse;
Example:
<!DOCTYPE html> <html> <head> <title>flexbox</title> <style> .gfg_flex { display: flex; flex-direction: row; background-color: green; text-align:center; } .gfg_flex > div { background-color: #f4f4f4; width: 100px; height:100px; margin: 10px; font-size: 40px; } h2 { text-align:center; } .geeks { font-size:40px; text-align:center; color:#009900; font-weight:bold; } </style> </head> <body> <div class = "geeks">GeeksforGeeks</div> <h2>flex-direction Property</h2> <div class="gfg_flex"> <div>Box A</div> <div>Box B</div> <div>Box C</div> <div>Box D</div> <div>Box E</div> </div> </body> </html> |
Output:
flex-wrap: The flex-wrap property is used to define the wrap of flex-items. If flex-wrap property set to wrap then browser’s window set the box. If browser window is smaller than elements then elements go down to the next line.
Syntax:
// Wrap flex items when necessary flex-wrap: wrap; // Flex items will not wrap flex-wrap: nowrap;
Example:
<!DOCTYPE html> <html> <head> <title>flex-wrap property</title> <style> .gfg_flex { display: flex; flex-wrap: wrap; text-align:center; background-color: green; } .gfg_flex > div { background-color: #f4f4f4; width: 100px; height:100px; margin: 10px; font-size: 40px; } h2 { text-align:center; } .geeks { font-size:40px; text-align:center; color:#009900; font-weight:bold; } </style> </head> <body> <div class = "geeks">GeeksforGeeks</div> <h2>flex-wrap Property</h2> <div class="gfg_flex"> <div>Box A</div> <div>Box B</div> <div>Box C</div> <div>Box D</div> <div>Box E</div> <div>Box F</div> <div>Box G</div> <div>Box H</div> <div>Box I</div> </div> </body> </html> |
Output:
Note: The flex-flow is a shorthand for flex-direction and flex-wrap.
Syntax:
flex-flow: row wrap;
justify-content: The justify-content property is used to align the flex items according to the main axis within a flexbox container.
Syntax:
// Aligns the flex items at the center justify-content: center; // The space is distributed around the flexbox items //and it also adds space before the first item and after the last one. justify-content: space-around; // Space between the lines justify-content: space-between; // Aligns the flex items at the beginning of the container justify-content: flex-start; // Aligns the flex items at the end of the container justify-content: flex-end;
Example:
<!DOCTYPE html> <html> <head> <title>justify flexbox property</title> <style> .flex1 { display: flex; justify-content: center; background-color: green; } .flex2 { display: flex; justify-content: space-around; background-color: green; } .flex3 { display: flex; justify-content: space-between; background-color: green; } .flex4 { display: flex; justify-content: flex-start; background-color: green; } .flex5 { display: flex; justify-content: flex-end; background-color: green; } .flex-items { background-color: #f4f4f4; width: 100px; height:50px; margin: 10px; text-align: center; font-size: 40px; } h2 { text-align:center; } .geeks { font-size:40px; text-align:center; color:#009900; font-weight:bold; } </style> </head> <body> <div class = "geeks">GeeksforGeeks</div> <h2>The justify-content Property</h2> <b>justify-content: center </b> <div class="flex1"> <div class="flex-items">1</div> <div class="flex-items">2</div> <div class="flex-items">3</div> </div> <br> <b>justify-content: space-around </b> <div class="flex2"> <div class="flex-items">1</div> <div class="flex-items">2</div> <div class="flex-items">3</div> </div> <br> <b>justify-content: space-between </b> <div class="flex3"> <div class="flex-items">1</div> <div class="flex-items">2</div> <div class="flex-items">3</div> </div> <br> <b>justify-content: flex-start </b> <div class="flex4"> <div class="flex-items">1</div> <div class="flex-items">2</div> <div class="flex-items">3</div> </div> <br> <b>justify-content: flex-end </b> <div class="flex5"> <div class="flex-items">1</div> <div class="flex-items">2</div> <div class="flex-items">3</div> </div> </body> </html> |
