Responsive four card feature using flexbox and grid

Hi @justEfere, 🙋‍♂️

Congratulations on completing this challenge! 🎉 You did a great job on the layout, it looks great! 👏

You can use percentage units to give relative size to the children 😄

<div class="container">
   <div class="container-item"></div>
</div>

.container {
    width: 100px;
}

.container-item {
    width: 50%;
}

This will make the .container-item to be 50% of its parent. So if you change the width of .container, the .container-item's width will also change.
