Working with containers in a web page could be tricky, especially if we need to manage large text. There's a CSS declaration which we need to fully understand in that matter: overflow.
When we create a container - let's call it "box" - the overflow declaration helps the browser to understand what to do with the eventual content that doesn't fit in the container. If the container has a fixed height, what will happens to the content that doesn't fit in the box?
When the box has not a fixed height, the content will fit in any case and the box will enlarge, giving the needed space to the content. When the height is fixed, we might need to use the overflow declaration.
The overflow declaration
There are four possible values for overflow:
1) visible
2) hidden
3) auto
4) scroll
