My DD is about to turn 2 so I'm a bit further on than you, this is my first too and I felt a bit clueless and worried about this too initially, especially as my DC is 'spirited'. I read 'How to Raise Your Spirited Child' which was useful and just recently 'How to Talk so Little Kids Will Listen' which takes a similar approach and was also useful.
For me, the first step is always managing expectations of behaviour within yourself and coming to terms with that. How much can you reasonable expect of your child and their age and stage of development? Etc. The next step is setting your child up for success, which you are already learning to do by removing things you don't want them to get their hands on. I don't just mean dangerous things. We can't reasonably expect a baby/toddler with no impulse control can learn not to touch things so to avoid the issue completely, the best thing is to remove it and the situation never arises.
The next step is trying to detract from a situation before a tantrum begins with things like distraction. Obviously this doesn't always work!
When a full on tantrum is under way then definitely do not give in if you've said no. Like PP said, you don't want to teach them that the more they scream the more likely they are to get x. I try a mixture of distraction and ignoring, making sure DC is safe. Or coming up with solutions 'what can we do so you will feel calmer?' etc.
I also avoid raising my voice and sharp admonishments to keep them only for things that are dangerous. This works well so far as she gets the message straight away as it's rare we do that.
I try to avoid saying no as much as possible, inevitably I still say it a lot! But try to focus on what we DO/CAN do rather than what we don't /cannot. E.g. oh DD I can see you are throwing your food onto the floor, we don't do that because it makes a mess and then mummy will have to clean it up instead of having that time to play with you. How about we put the food we don't want on this spare plate instead? - or if you have finished, let's go and find something we can throw, like a ball. I know your DC is younger but its good to get in good habits for yourself so you feel confident in dealing with the behaviour as it gets stronger as they get bigger and stronger.
FWIW my DD has far fewer tantrums now than she did at 1 and they are generally shorter and less intense. Obviously sometimes you try everything and it doesn't work and they scream for 45 minutes and you don't even know why, but that's kids for you
