Blend [Optional]
Describes how a layer should blend with the layer's direct parent and the layer's background and layers below the layer. Default value is 'normal'.
The equivalent html code looks like <div style="mix-blend-mode:normal|multiply|screen|overlay|darken|lighten|color-dodge|color-burn|hard-light|soft-light|difference|exclusion|luminosity" >
Note: use with caution, IE does not support this feature.
