CSS VARIABLES
In CSS, var() function can be used to insert a CSS variable in the CSS code.
This is very useful especially when a value or color is used repeatedly in the code.
The variable is declared inside the :root selector for global usage as shown and
then the var() function is called with the name of the variable inside.
:root {
--testBlue: #95caff;
--testRed: #ff6c6c;
}
p {
color: var(--testRed);
background-color: var(--testBlue);
}
Output:
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
