Some tips.<p>Keep your layouts flexible: 
* Avoid specifying widths and especially heights of individual elements unless really necessary. Allow the content to determine dimensions.
* Set percentage based widths on overall containers (columns &#x2F; grids). Allow these to constrain the dimensions of elements within. (Simplify your page structure as much as possible and don&#x27;t overuse these.)
* Use max-width to prevent elements from exceeding the dimensions of their containers:
	img {max-width: 100%;}
