Highlighters can be used to provide visual emphasis to an element; during user interactions for example.

In the above demo, we listen to the paper for the `cell:pointerclick` event, then highlight the cell that was clicked.

    paper.on('cell:pointerclick', function(cellView) {
        cellView.highlight();
    });

As you can see it is possible to highlight a cell as follows:

    cellView.highlight();

Unhighlighting a cell is simple too:

    cellView.unhighlight();

To highlight a cell using a specific highlighter (and options):

    cellView.highlight(null/* defaults to cellView.el */, {
        highlighter: {
            name: 'stroke',
            options: {
                width: 3
            }
        }
    });

Or you can specify just the highlighter's name (its default options will be used):

    cellView.highlight(null/* defaults to cellView.el */, {
        highlighter: 'stroke'
    });
