I have a creative vision I am currently pursuing. My goal is to create a div that displays as a fixed dimension box where different javascript functions will gradually input text. As the number of lines of text surpasses the height of the box, I envision a scrollbar appearing beside the box. This way, users can scroll through the text inside while maintaining the box's fixed height.
Does anyone have ideas on how this could be achieved?
With the power of CSS, achieving this effect is easy:
div{
overflow-y: scroll
}
You also have the option to use overflow-y: auto as suggested by @tw16
When there is an excess of text, the scrollbar can be utilized using the following CSS rule:
div{
overflow-y: auto
}
To see this in action, check out this live example: http://jsfiddle.net/RMpFu/
To add scroll functionality in CSS, you can use the overflow property:
document.querySelector("div").style.overflowY = "scroll"; //For vertical scrolling
document.querySelector("div").style.overflowX = "scroll"; //For horizontal scrolling
document.querySelector("div").style.overflow = "scroll"; //For both directions ;)
If you only want the scroll bar to appear when needed, you can opt for this approach instead:
document.querySelector("div").style.overflow = "auto"; //Using JavaScript
//-or-
div{
overflow: auto; /*In CSS*/
}
<script type="text/javascript">
$(document).ready(function() {
$('.holeEvent').hover(function() {
$(this).toggleClass('holeEvent holeEvent2');
});
});
</script>
<style type="text/css>
.eventHole {
height: 50px;
overflow-y: hidden;
}
.eventHole2 {
height: 50px;
overflow-y: scroll;
}
</style>
<div class="eventHole2"></div>
