The custom marker created with Leaflet using divIcon does not seem to be styled with the specified

I'm currently working on customizing the leaflet marker using a divIcon and custom HTML. My aim is to have my marker displayed similarly to this example: https://i.sstatic.net/a5RnY.png

So far, I've managed to create a marker and a divIcon with the following code:

    leaflet.marker(NETHERLANDS_CENTER, {
      icon: leaflet.divIcon({
        html: '<div class="vehicle-container"><div><img src="../../assets/images/bus-solid.svg" width="16" height="16"/></div><div><p>HTM</p></div></div>',
      })
    }).addTo(this.map);

The map displays the marker as follows:

This piece of code is in my Angular map component that comes with its own CSS file. However, no matter what I try to do in the CSS file, it seems to have no effect on the styling of the marker displayed on the map.

I've experimented with customizing the vehicle-container class in various ways, but none seem to take effect. I even tried using the className property of the divIconOptions, which removed the white square, yet did not change anything when attempting to customize the CSS for that class name.

I also inspected the marker and noticed it was wrapped in an element with the class .leaflet-div-icon. Despite trying to modify the styling of this class, I was not successful.

Is there a special trick to styling leaflet markers, or am I missing something?

Answer №1

If you want to include inline styles in a more structured manner, follow this example:

 // Your styles can be included like this
 const markerHtmlStyles = `
      background-color: #fff;
      width: fit-content;
      height: 3rem;`

leaflet.marker(NETHERLANDS_CENTER, {
      icon: leaflet.divIcon({
        html: `<div style="${markerHtmlStyles}" class="vehicle-container"><div><img src="../../assets/images/bus-solid.svg" width="16" height="16"/></div><div><p>HTM</p></div></div>`,
      })
    }).addTo(this.map);

To prevent the white square, ensure that the className is set to '' and adjust the CSS file for the markers to customize their appearance.

There may be alternative methods, but this approach offers a quick solution.
