border radius of a div inside another div is overlapping - html

Question

I am making this card using React, HTML and CSS
Here is my Code:
<div className="plan">
<div className="plan-name">
<h5>BASIC</h5>
</div>
<div className="plan-price">
<h2>$ 6.99</h2>
<span>Screen Availabilty Simultaneously</span>
</div>
<div className="plan-details">
<ul>
<li>
<span>
<CheckIcon />
</span>
Access to All Library in Unlimited
</li>
<li>New Content Monthly</li>
<li>Available on PC, Smartphones and tablet</li>
<li>Drawing in Color</li>
<li>Color in Very High Quality</li>
<li>Canceable at Any Time</li>
</ul>
</div>
</div>
CSS:
.plan {
border-radius: 25px;
overflow: hidden;
background-color: #fff;
}
.plan-name {
background-color: #3e104f;
padding: 25px 0;
border-style: solid;
border-width: 0;
border-bottom-left-radius: 20px;
border-bottom-right-radius: 20px;
}
.plan-price {
color: #3e104f;
background-color: #fff;
padding: 35px 0;
}
.plan-details {
background-color: #3e104f;
height: 100%;
border-radius: 20px;
}
Output:
But I am getting the white border which I have highlighted above, on all corners. Can anyone tell me where am I doing wrong? Or from where it is coming? How do I hide it?

Answer 1

It's normal behavior, you have no mistake in your CSS.
Possible solution is to make something like this
.plan {margin-top: 25px; overflow: visible;} /* here just remove overflow: hidden to show .plan-name outside of .plan */
.plan-name {margin-top: -25px; border-top-right-radius: 25px; border-top-left-radius: 25px;}
Using this code .plan's radius is hidden underneath .plan-name and isn't visible in corners.

Answer 2

just adding .plan {overflow: auto;} works for me as well
