Solution 1:[1]

I added to .flex-container2 this properties:

text-align:center;
background-color:#fff;
border-radius:20px;
padding:15px;
height:430px;

Also for h1 tag in css:

font-size:21px;

for p tag in css:

font-size:15px;

Finally image size is:

width:250px;
height:250px;

And looks like this:
