The <code>em</code> unit is relative to the <code>font-size</code> of its <b>parent element</b>. <code>rem</code> stands for \"root em\", it's only relative to the <b>root element</b> (<code>html</code>). It makes <code>rem</code> unit more predictable and easier to manage in large websites."

          "text": "<code>rem</code> unit is extremely beneficial for responsive design. Since <code>rem</code> is relative to the root element, changing the root <code>font-size</code> allows you to <b>adjust the size of all elements</b> defined in <code>rem</code>. This can be done by using media queries, allowing to make different font sizes for different screen breakpoints."

          "@type": "Answer",
          "text": "Using <code>rem</code> unit can significantly improve the accessibility of website. Some users may adjust their browser's default font size for better reading experience. Since <code>rem</code> unit is relative to this base <code>font-size</code>, it allows the layout and spacing of your website to <b>adjust according to the user's preferences</b>, which improves the UX."

          "@type": "Answer",
          "text": "Yes, <code>rem</code> unit can be used in combination with another CSS unit. It can provide more flexibility in your design. For example, you may use <code>px</code> for <code>border-width</code> (which don't need to scale with text size) and <code>rem</code> unit for <code>padding</code> (which does)."

          "@type": "Answer",
          "text": "The base <code>font-size</code> for <code>rem</code> unit is set on the <b>root element</b> (<code>html</code>) by using <code>font-size</code> style property. For example, if you want the base <code>font-size</code> to be <code>20px</code>, you might use: <code>html { font-size: 20px; }</code>. All <code>rem</code> units will be using that size."
