Differences between 1fr 1fr, auto auto, and 50% 50% in CSS Grid

The article on Frontend Masters discusses the differences between three popular ways to define proportions in CSS Grid: 1fr 1fr, auto auto, and 50% 50%. The author explains that 'fr' stands for fractional units, allowing the container to be divided into proportions. In the case of 1fr 1fr, two columns are evenly split, which can be ideal for simple layouts. On the other hand, auto auto allows for dynamic adjustment of columns to their content. This is important in situations where we cannot predict how much space our elements will take up. Finally, using 50% 50% provides rigid divisions, which gives greater control over layout distribution. The author emphasizes that the choice of method should depend on the context of the project and visual requirements. With a well-thought-out layout strategy, we can effectively utilize CSS Grid in our projects, leading to better user experiences and more responsive designs.
