Run the script and it will insert a new line there the px value is converted to a rem value. </p> <p>You need to edit the code to modify your rem base matching the one you use in your own CSS. The default value is 16.</p> <p>Example: font-size: 12px; (run the script with the cursor in this line) font-size: 0.75rem (new line added by script) </p>
