Give all div elements within a div 100% height if container has flexible height

Question

I have a div ( payslip-column-container ) that contains three child div ( payslip-column ) elements

<div class="payslip-column-container">
            <div class="payslip-column payments">
              ...
            </div>
            <div class="payslip-column deductions">
             ...
            </div>
            <div class="payslip-column payment-frequency">
                ...
            </div>
</div>


.payslip-column-container {
    height: 350px;
}

.payslip-column {
    height: 100%;
}

I wish to make the three child div elements be 100% the height of the container. This works fine above if I give the payslip-column-container div a specific height (350px)

If I give the container div a height: fit-content then it gets the height of the first child div (which is the tallest) but the othertwo divs revert back to not respecting the 100% height setting

I want my container div to be the height of the tallest child div and then the other two divs to be the same height as the tallest

Can I achieve this with this markup?

Answer 1

you can achieve this by flex

 .payslip-column-container { display: flex; } .payslip-column { flex: 1 1 0; border: 1px solid red; max-width: 100%; }
