How to Eliminate Whitespace and Scrolling Issues with Canvas in a Div Container?

Resolving White Space and Excessive Scrolling in Canvas

When embedding a canvas element within a div container, certain styling issues may arise. One common issue is the presence of white space at the bottom of the canvas and excessive scrolling.

Cause:
By default, canvas is rendered as an inline element. This can result in unwanted whitespace and vertical alignment issues when placed within a block-level div container.

Solution:

1. Make Canvas a Block Element:
   Alter the CSS of the canvas element to display it as a block element:

   canvas {
     display: block;
   }

2. Vertical Alignment:
   Alternatively, use CSS vertical alignment to position the canvas correctly within the container:

   canvas {
     vertical-align: top;
   }

Implementation:

Modify the provided code as follows:

.screen CSS:

.screen {
  background: red;
  height: 100px;
  width: 300px;
  overflow: auto;
  border-radius: 20px;
}
canvas {
  display: block;
}

::-webkit-scrollbar {
  width: 0px;
  height: 0px;
}

This customization ensures that the canvas behaves as a block element, eliminating whitespace and excessive scrolling issues.
