Is document.createElement() generating elements in a new way?

When I create a new element, such as div, it automatically generates both an opening and closing tag. However, when creating an element like canvas, only the opening tag is generated. Why does this happen?

document.createElement('div');

This code results in <div></div>.

document.createElement('canvas');

Executing this code will create <canvas>. If a child element is appended to it, then it will become

<canvas>childTag</canvas>
. Are there specific reasons for this behavior? Which other elements behave similarly to canvas? And which elements act like the aforementioned div? Is the closing tag for canvas optional?

Answer №1

This particular issue is exclusive to the Live View feature in your development tools. The closing tag is present and absolutely necessary.

Chrome likely behaves this way because it doesn't display any content (although <canvas> may contain hidden content).

You can verify this by accessing the outerHTML property of the element you've created:

console.log(document.createElement('canvas').outerHTML);
