2. If simple present, simple present
SUMMARY
Conditional 0:
If simple present, simple present
First conditional:
If present tense, any form of the future
Second conditional:
If + past (simple or continuous), would + verb
Third conditional:
If + past perfect (S or C), would have + p. participle

3. MIXED CONDITIONALS
When we talk about mixed conditionals, we are referring to conditional sentences that combine two different types of conditional patterns. These combinations are not all that frequent, but the most common combination is when we have a type 3 conditional in the if-clause (if + past perfect) followed by a type 2 conditional (would + infinitive) in the main clause.  
mixed third / second conditional 
With this combination we are contrasting an imagined or real event in the past with the present result of that. Consider these examples: 
If he'd taken the medication, he wouldn't still be lying sick in bed. 
If she'd taken reasonable precautions, she wouldn't be pregnant now. 
If he hadn't run after the car thief and suffered a heart attack, he'd probably be alive today.

4. MIXED CONDITIONALS mixed second / third conditional
The other possibility, though I think this is less common, is when we have a type 2 conditional in the if-clause (if + past simple) followed by a type 3 conditional (would've + past participle) in the main clause. 
With this combination, we are describing ongoing circumstances in relation to a previous past event. Consider these examples: 
If you weren't such a poor dancer, you would've got a job in the chorus line in that musical.
