Responsive Design FAQs
Why use REM instead of PX for responsive design?
REM (Root EM) units are relative to the root font size of the document. This allows your entire layout to scale proportionately if a user changes their browser's default font size, making your site more accessible.
Is 1rem always 16 pixels?
By default, most browsers have a root font size of 16px, so 1rem equals 16px. However, if the root font size is changed via CSS (e.g., html { font-size: 18px; }), 1rem will become 18px.
How do I convert 1.25rem to PX?
Multiply the REM value by your base font size. If your base is 16px, then 1.25rem × 16 = 20px.
