The phase between current and voltage in LC circuit
If the capacitor and inductor are in series AND the operating frequency is such that the capacitive reactance is greater than the inductive reactance then, the net impedance presented is capacitive and when that happens, the current leads the applied voltage.

So \$X_C\$ needs to be greater than \$X_L\$.

If the inductor and capacitor are in parallel then the opposite applies.
