Symptom: Text “suddenly” disappeared

Possible Fix: Set position:relative on the div whose text is missing! I added position:relative for one of its parent div then had the error. Reference

Symptom: Unusual/Excessive/Too much white space for a floating div

Possible Fix: set display:inline on your div. This is likely to be the silver bullet for the problem. Reference

Symptom: Negative margin clipped/cut off/not shown completely
