In this article, I am going to explain how to create a responsive timeline design with collapse using Twitter Bootstrap. Ever since facebook introduced it, designers have been coming up with various forms of timeline designs to depict a story or history of events on a webpage. So, I thought I could make use of Twitter Bootstrap to quickly write a timeline along with bootstrap's collapse component.
Libraries Used
-- jQuery-- Twitter Bootstrap
-- Animate.css (Optional)

$('#experience').find('.timeline-item:not(:first)').each(function(i){
var element = $(this),
itemsDelay = ( isNaN($(this).data('animation-delay')) ? 50 : $(this).data('animation-delay'));
element.css('opacity', 0).one('inview', function(isInView) {
if (isInView){
setTimeout(function(){

} , itemsDelay * (i * 2));
}
});
});
How it works
Before we get into how it works, please have a look at Bootstrap collapse plugin here and understand how it works.
1. CSS3 Media queries are used to adjust the style according to the device size. The meta tag (name=viewport) detects the device width.
2. To set the collapsible element to be open by default use the in class (example :index.html - line 47). In this example the first section of the collapse/timeline is made to be open on load. To set the collapsible element to be closed, use class="collapsed" on the timeline-button. (example :index.html - line :65)
3. The jquery code in app.js opens all the collapsible sections if the screen size is below 768px, in case of mobile or a tablet.
4. I have also added some animation using Animate.css by Daniel Eden. This is totally optional.

Recently, I experimented with a Responsive Timeline with Bootstrap Collapse, and it ended up being a great way to expose information to an audience in a structured manner. As a Dissertation Proposal Writers, I often must visualize complex research milestones or timelines to clients or collaborators. With this design, I can portray the stages of a dissertation process—like research proposal submission, data collection, and final defense—in a rather aesthetic way.
