Disable right-click

I've always wondered why and how some websites disable right-click so you can't save any content from them, or they stop you from inspecting elements. I learned that you can do it with JavaScript with the following code:

document.addEventListener('contextmenu', event => event.preventDefault());

I am already using it on this particular page, so if you try to right-click it will not work. A way to work around this is to disable JavaScript on your browser and refresh.

Disable Highlighting

Now if we want people to get more irritated we can always add a way to stop them from highlighting text with the following CSS properties:

.noselect {
            -webkit-touch-callout: none; /* iOS Safari */
              -webkit-user-select: none; /* Safari */
               -khtml-user-select: none; /* Konqueror HTML */
                 -moz-user-select: none; /* Old versions of Firefox */
                  -ms-user-select: none; /* Internet Explorer/Edge */
                      user-select: none; /* Non-prefixed version, currently
                                            supported by Chrome, Opera and Firefox */

You can highlight everything in this page except for this paragraph:

STUFF YOU CAN'T HIGHLIGHT

It can be used on most HTML tags (and can be set as ID too).
