Make text scrollable within div

问题

I am looking to make some lengthy text contained into a div where the text can be viewed by scrolling up or down. Right now the "description" text is rendered like so <%= @pin.description.html_safe %> and is inside a <div class="panel-body> (I'm using Bootstrap).

回答1:

Give your div a height and set overflow: scroll

#elementId{
    height: 200px;
    overflow: scroll;
}

If you only want it to scroll up/down and not left/right use:

overflow-y: scroll;
