Too Long; Didn't Read
Many front-end developers are biased against UI/UX designers and do not trust them. Many myths prevent effective communication between developers and designers. The most frustrating thing is when a designer or tester does not like your decision and rearrange it as an open bug, although there is no bug at all at all. The best advice at this point is: trust your colleague more — he surely knows what he’s doing. There are many more myths, but the main idea that I want to convey is this: all designers are people, not designers.
