What is REM?
REM, or 'root-em,' is a scalable CSS unit of measurement associated with the font size of the root element in an HTML document. Mainly, the <html> element denotes the root element in the HTML file whereas, the font size is typically fixed on the <body> element.
The REM unit deals with the element's text size, but the 'em' unit raises to the nearest text size of the parent or element's font size.
Let us understand the REM further with an example: if you set the root element with the size of 16 pixels, 1rem would be 16px. Similarly, if you alter the font size of the root to 20 pixels then one rem would be updated by around 20 pixels.
Users can fix the REM font size element in pixels or adjust to the default font size. In the case of unspecified pixel value, the unit will receive from parent elements which by default is 16px.
The REM units are commonly used in stylesheets which enable users to define sizes consistently and more flexibly. The reason is that altering the size of the root element will significantly affect all your REM-based sizes throughout the entire document.
What is PX?
The 'PX' refers to 'Pixels' in CSS. Simply put, this CSS unit is widely used to express the element's size and distances on web pages. Pixel is the unit that is fixed size, meaning the value of pixel remains the same for any screen resolution you use. You have to specify dimensions in the pixel unit to take the control of the size of elements so that you can make consistent layouts easily.
However, for a responsive web design, pixels are not an approachable option for web designers. It is because they are not adaptive to various screen resolutions therefore designers use them with some other units like viewpoint or percentage units to create flexible page layouts.
Also, when we see fixed-sized pixels on multiple screen densities it may cause readability problems, or users have to control the size of text for improved visibility which is such a hassle. This is why web designers have to use proper relative units with it.
