— I have written a html and css code and prepared a page template
— But if i increase the browser size all the <div> 's are re arranging
— It is looking as expected only when i put the size of the browser as of I developed it
— Or at least search for "px" in your css, and find out if you have any constants
— Try bootstrap https://getbootstrap.com/
— Px is placed everywhere
— Is it replaced with % ??
