Popover for long text without spaces

Since 2012 another solution for word-wrap is:

overflow-wrap:anywhere;

More information: Difference between overflow-wrap and word-break?

Examples of use: https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-wrap

edit: word-break: break-word is officially deprecated; see https://drafts.csswg.org/css-text-3/#valdef-word-break-break-word

That's because Twitter bootstrap applies a max-width property to the .popover box by default (Which is max-width: 276px;).

There are two options:

1) Override the max-width by reseting that to none as:

.popover {
    max-width: none;
}

2) Or use word-wrap: break-word; CSS declaration for the popover content box as:

.popover-content {
    word-wrap: break-word;
}
