Potential gradient is the negative of the electric field. Does the negative (here) means that its direction is opposite to electric field.?

If it does mean this, How is the direction of the potential gradient opposite to that of electric field..? Explanations would be helpful...

One thing necessary about Potential. It's simply the work done in moving an electric charge against the electrical force. Thus, The negative sign actually says that the work done is against the electric force (either attraction or repulsion). Or in other words, electric potential decreases in the direction of electric field. Hence, you're quite right about the concept.

This link is explains in an imagery way.
