Answer 1

For this, you can use CSS property user-select with value none:
HTML:

<div class="no-select">
<!-- Content here is disabled for user selection -->
</div>

CSS:

.no-select {
    -moz-user-select: none;
    -webkit-user-select: none;
    -ms-user-select: none;
    -o-user-select: none;
    user-select: none;
}

Also, you can use JS PL for it, but if user disable JS, then him can get around it.
