[plugin:SidePosts Widget] changing line thickness between

Thanks shilojean!

About the line thikness is not defined in the wdget styles. It takes it from your theme styles. So, you have to define that considering how is your theme’ style.

There is nothing to change in the plugin CSS file to do that, because it’s not there. You need to add it to the file.

If the sample style provided with the widget works for you, then I suggest to add this at the very bottom of the CSS file:

#sidebar ul li.widget_sideposts ul li {
	border-bottom: 3px dotted #ff0000;
	}

This would draw a dotted line 3 pixels thick.

Another example:

#sidebar ul li.widget_sideposts ul li {
	border-bottom: 3px solid blue;
	}

This will change the color to blue, solid line and 3 pixels thick.

Rememeber to save a copy of the modified CSS file, to prevent loosing changes when updating the plugin 😉

Hope this is what you were looking for. If it not works for you, provide me with the site url to check the styles and look for a best way to do it.
