hi @Vrajang_Shroff your question is not related to Webflow but about how CSS Grid works. May be someone will have time to give you lessons how CSS Grid works but on internet is large amount of articles and video-tutorials.
I will suggest that with help of browser you will find some tutorial about this topic to get understanding ho CSS Grid work. All these tutorials will be in code so it may be a bit challenging if you never coded before but it is nothing hard to understand.
