Using rem units allows for easy control of full page size to make it responsive.
For example:
div{
font-size:20rem;
}
@media only screen and (max-width: 576px)
{
html{
font-size:20%;
}
}
But what can we do when using px units instead?
If you require precise calculations for values in your stylesheet, consider utilizing the calc() function. For instance:
width: calc(100% - 20px);
Don't forget to consult the documentation for further information.
