Set tooltip on custom leafletjs control

Question

I have made several custom buttons in Leafletjs - now I would like to add a hover-over tooltip to explain what the button does. I've tried putting a "title:" and "tooltip:" in the options but still do not see the text when I hover over the control.

var load = L.Control.extend({
    options: {
        position: 'topright'

    },

    onAdd: function(map) {
        var container = L.DomUtil.create('div', 'leaflet-bar leaflet-control leaflet-control-load-points');

        //container.style.backgroundColor = 'white';
        container.style.width = '25px';
        container.style.height = '25px';

        container.onclick = function() {
            clear_markers(markers);
            load_markers(markers);
        }
        return container;
    },
});

The URL seems to be broken, a mere six years later. Whart on earth are the inter-tubes coming to??!! — Mawg says reinstate Monica, Jan 18 '21 at 11:04

To answer my own question I was using the wrong approach to add the title option. By creating the container first and then setting the title after I was able to populate the title field and have a tooltip work on hover over.

var load = L.Control.extend({
    options: {position: 'topright'},
    onAdd: function(map) {
        var container = L.DomUtil.create('div', 'leaflet-bar leaflet-control leaflet-control-load');
        container.title = "Enter Tooltip Here"
    }
});

I cannot get this to work with HTML in the title :-( – Mawg says reinstate Monica Jan 18 '21 at 11:03
