I have typed it in above the code.

Let me fix that, the div element doesnt show on the third line of my explanation.
I am instructed to give the first
div element
in the user editable region the classes ‘marker’ and ‘one’.
When i have done that, it says:
You should add the class one to the first marker div element.

Hello!

Nice attempt.

Class values should be listed within the same quotation marks.

If you add the one to the same quotation marks as the marker it will pass. Leave a space after marker then add the one before the quotation mark.

Example: class='value value2'

Happy coding!

And it should have quotation marks, not apostrophes.

Example: class="value1 value2"

Hello!

Those are single quotation marks, as per syntex, we can use either single 
or double quotation marks.  I checked and both ways work.

"Like when we wish 'to quote something' within double quotation marks."  
or
'Like this when we use "single quotation marks" on the external quotation.'
