Please see the cases below :

I’m trying to align above h1 (i.e Add Maintenance) with below field label. But the left alignment looks different with different letters.
In example 1 A in Add Maintenance “touches” the left border.
In example 2 C doesn’t touch the left border and has some space.
In example 3 B doesn’t touch the left border and has some space but space is slightly bigger than in example 2.
How do I align them in a straight line?
Side note :
This is all same site, I just changed the value of h1 text
Try different font because in Arial “B” and “C” letter has some space before it, but “A” does not.
