How can you edit only one h2 code? I'll was trying to edit the codes so that only one or two h2 headings can be different from the rest(such as the color or font size). Is this possible, it seems like I tried everything? Also is there a way that I can convert some h2 heading codes to h3? Can either of these be done using css or html(how will I use html to do this?)? Thank you in advance.
