Take the TXID of any transaction you are interested in, paste it in to the top and click "Search", and then click on the symbol of the piece of paper which says "Raw". It will give you a color coded breakdown of all the parts of the transaction data. Hover your mouse over each part to see what it is.

If you are not sure about how to understand the locking scripts, then look the same transaction up at https://mempool.space/ and click the "Details" button to see the locking scripts decoded with relevant bytes replaced with OP codes.
