//applying styles for wms layer
var fill = new ol.style.Fill({color: 'rgba(237, 26, 170, 0.82)'});
var stroke = new ol.style.Stroke({color: '#4A12ED',width: 1.25});
var text = new ol.style.Text({color: '#F21A6C'});

var styles = [new ol.style.Style({
    image: new ol.style.Circle({

          })
     })
});

but styles are not applied error messages are not available in console I want to know what is wrong with this code and how to apply styles properly.

Answer 1

The ol3 styles are meant to be used for vector layers, not for WMS layers. But you could set the styles , SLD or SLD_BODY property manually in the params to set a style.
