In CSS, absolute positioning is a way to position an element relative to its nearest positioned ancestor element rather than to the viewport or the normal flow of the document.
To use absolute positioning, you first need to set the position property of an ancestor element to a value other than "static", such as "relative" or "absolute".
Understand the difference between Javascript "==" and "===" operators:
In JavaScript, "==" is the equality operator and "===" is the strict equality operator.
The main difference between the two is that "==" compares values for equality and performs type coercion if necessary, while "===" compares both values and types for equality.
For example:
If you use "==" to compare the number 5 to the string "5", the comparison will return true because JavaScript will transform the string to a number before performing the comparison.
