  • hide img tag if src is empty but without javascript/jQuery or css3 You can use [attr=val] selector

img[src=""] { display: none; }

The above selector will simply match, if the src attribute has no value. This selector is a general one and will match all the img tag in the document with an empty src, if you want to target specific ones, than use more specific selector like

.class_name img[src=""] { display: none; }
