How can we better manage our emotions as parents when toddler throws tantrum?

It has been really challenging whenever our toddler throws tantrum, does not do what we want her to do, and is fussy with eating. My husband loses his temper very easily whenever such things happen. I, on the other hand, try to stay calm and always wish that he could too, as I have learnt that there are better ways to handle such situations instead of getting angry. The atmosphere also feels very tense because there is a lot of crying from our toddler and shouting from my husband, and I do not like it. It also feels like my husband and I are not on the same page when it comes to our way of parenting. We sometimes question each other when we do certain things, and it feels like the one being questioned is being blamed. I just want more joy and peace in the house, and less shouting and unhappiness. Are there any tips on how to better manage our emotions while facing challenges with our toddler?
