What I learned

I initially felt I wouldn't be able to accomplish it. But once I started thinking about what the layout should be, I was able to develop something that was near to the solution. MDN documentation aided me along the way.

A few difficulties I encountered: horizontal and vertical item centering. How do we center it without the thing bouncing about and shrinking?

Some code snippets I found helpful but doesn't help entirely, see below:

<div class="container">
  <div class="child"></div>
</div>

.container {
  font-family: arial;
  font-size: 24px;
  margin: 25px;
  width: 350px;
  height: 200px;
  outline: dashed 1px black;
  /* Setup */
  position: relative;
}

.child {
  width: 50px;
  height: 50px;
  background-color: red;
  /* Center vertically and horizontally */
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

• freeCodeCamp - Had the snippet from here.

Continued development

I need a bit more practice with the flexbox.

Useful resources

• MDN Docs - This helped me revise some snippet. Very easy to comprehend.
