Does Charles Schwab allow you to buy fractional shares?

Excuse me, could you please clarify something for me? I've been hearing a lot about fractional shares lately, and I'm wondering if Charles Schwab, being a reputable financial institution, permits their clients to purchase fractional shares? I'm interested in diversifying my portfolio but might not have enough capital to buy whole shares of certain companies. Would I be able to invest in those companies through Charles Schwab by purchasing fractional shares? I'd appreciate your insights on this matter. Thank you.
