Since its my first Project Learnt how to create a website according to the requirement given and also styling is difficult part which took most of my time so my plan is to improvise in styling next time

First challenge is i was not able to get the box under which the image and the rest of the text goes into so used field set at first and then by styling itself i tried to come up with the solution Next Thing is alignment according to the design provided was tough so in this case tried adding padding at first with different outcome of number but then used margin property and justify content in css

i need help in the design part where i need to understand how can reduce the size of the box and come up with the exact match of the design and also how to add border at which place any clue to identify so it can be useful for me next time when i am trying something new
