How can I use Flexbox to create a calculator keypad with keys of varying heights and widths?

Understanding the Flexbox Layout for Calculator Keypad

Flexbox provides a versatile method for arranging elements in a flexible and responsive manner. In this scenario, we aim to build a calculator keypad using flexbox while addressing the specific requirement of having keys of varying heights and widths.

Challenges in Implementing Varying Key Sizes

Initially, setting flex-direction as column was suggested to double the height of a key. However, this approach does not allow for doubling the width of another key.

Wrapping Uneven Keys in Flex Containers

To overcome this challenge, we can wrap the uneven keys in their own flex containers. By doing so, we create separate flexbox layouts tailored to their specific needs.

Custom Flexbox Layout for Uneven Keys

Here's how the CSS for the custom flexbox layout looks like:

#anomaly-keys-wrapper {
    display: flex;
    width: 100%;
}

#anomaly-keys-wrapper > section:first-child {
    display: flex;
    flex-wrap: wrap;
    width: 75%;
}

#anomaly-keys-wrapper > section:first-child > div {
    flex: 1 0 33.33%;
}

#anomaly-keys-wrapper > section:first-child > div:nth-child(4) {
    flex-basis: 66.67%;
}

#anomaly-keys-wrapper > section:last-child {
    width: 25%;
    display: flex;
    flex-direction: column;
}

#anomaly-keys-wrapper .tall {
    width: 100%;
    flex: 1;
}

This nested flexbox layout enables us to control the height and width of specific keys independently.

Conclusion

By carefully designing the flexbox layout and wrapping uneven keys in their own containers, we can successfully create a calculator keypad that meets the specifications of having keys of varying heights and widths. This approach provides us with a flexible and responsive layout that ensures the keypad adapts well to different screen sizes and devices.
