How to create a new html element?
html, javascript
Solution
There isn't really a reason to do that.
When you want to create an element with red background, you should use an existing element and assign a CSS class to it which has red background (like `<span class="test">`) .
Problem
I tried to create a new HTML element, called test: `<test>some text</test>` I tried to prototyping it like this: `HTMLUnknownElement.prototype.style.backgroundColor = "red";` but it doesn't work. Could you please help me, how to manage it? Thanks in advance,
