I am currently working on Building a Lightning Component, i am facing issue of size of each grid when i put layout in it there sizes are changed, all i want exactly same square sizes of 6 grid with 2 rows & 3 column in it. No matter how much i put layouts in it, it doesn't change it's size. Please help me in this. i searched a lot but haven't found anything which help me in it's Height, i am able to manage its width using
"slds-col slds-size--1-of-1 slds-large-size_4-of-12"
for column width but it doesn't acquire it's height and there is lot's of space remaining at the bottom which i don't want.
