Double dash HTML error on iOS

Tell us what’s happening:

The system on iOS is automatically changing the dash so I had to create all comments like this in order to proceed ( <!- - , - -> ). Once I typed them in, I would remove the space so the interface would recognize this. The example below shows me using the technique I described on the first portion only. It corrects the double dash to “-—“ in the interface.

Thank you.

Your code so far


<!--
<h1>Hello World</h1>
-->
<h2>CatPhotoApp</h2>

<!-—
<p>Kitty ipsum dolor sit amet, shed everywhere shed everywhere stretching attack your ankles chase the red dot, hairball run catnip eat the grass sniff.</p>
-—>
