Difference between /* Content */ and <!-- Content --!>

Hi, I am watching a video on CSS Comments and got confused about its shortcut. In order to opt out contents, I am supposed to use Command key + / but it comes up with <!-- --!> instead of /* / as shown on the video. I am curious what's the difference between them and how I can make it work as / */. (I assume that they play the same role though.) Thanks a lot!

These are comment identifiers for two different languages. The "<!-- --!>" sequence is for comments in HTML code, and the "/* */" sequence is for CSS code.

If you have both kinds of code in the same file (such as when you use <script> tags), it's possible that your editor has a bug and it got confused about what kind of code was being entered on that line.
