I have a mobile website, which shows entries by a user. The entries' style is similar to that of twitter entries or facebook entries. So along with each entries, if the user had entered some comments, a note icon will be shown at the end of that particular entry. When the user clicks the note icon, the comment will be displayed below the entry by expanding the entry. My question is should the comment contain a close button (a close icon at the top right)? At present you can click on the note icon once again to toggle the display.
Below is the screenshot. Sorry that I had to blur the things out. When I click the note icon the notes (comments) section (the grey box) shows below. Currently there is no close button on the top right. What would be the best user experience considering the beauty of the page as well. There will be only one note per entry.
