How to bring different elements into the viewport with jquery?

I have 3 elements that show/hide their contents when clicked on.
What I am aiming for: Click on element 1, brings the entire div into view. If I then click on element 2, the second div is brought into view.
What happens currently: Click on element 1, brings the entire div into view. Scroll down a bit and click on element 2, it scrolls back up to display the entire first div instead of the second div.
I believe the issue is that I have .content as the parameter in the scrollTop function but I haven't been able to figure out what I should put in there to address the issue.
My jquery/javascript is here:
$(document).ready(function(){
$(".flippy1").click(function(){
$(this).parent().children(".content").slideToggle(); //toggles the content
setTimeout(function(){
$('body').animate({scrollTop:$('.content').offset().top},200)
}, 200); //delay of 200 ms to let the entire slidetoggle animation finish, then scrolls to the top of the div
});
});
HTML:
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="flippy1">
<h2>Experience</h2>
</div>
<div class="content">
content goes here
</div>
</div>
</div>
<div class="row">
<div class="col-md-12">
<div class="flippy1">
<h2>Dogs</h2>
</div>
<div class="content">
contents goes here
</div>
</div>
</div>
<div class="row">
<div class="col-md-12">
<div class="flippy1">
<h2>Cats</h2>
</div>
<div class="content">
more content
</div>
</div>
</div>
</div>

The solution for me has been to use $("html,body") when animating scrollTop property. Some browsers do not play nicely with $("body") alone, although I have no proper explanation for this.
Second problem is you're referencing $(".content") in your timeout function. This animates scrollTop to the first occurrence of .content, not necessarily the clicked occurrence. But, we can do one better:
Third, and not a problem but a better way to handle, is to use the callback function of slideToggle: this function is code that gets executed only after slideToggle finishes. Do this rather than set a timeout. Timeout length is arbitrary, for example in a very old, very slow browser, 200ms may not be long enough duration to wait.
See the updates below:
$(document).ready(function(){
$(".flippy1").click(function(){
$(this).parent().children(".content").slideToggle( function(){
$('body,html').animate({scrollTop: $(this).offset().top},200);
});
});
});
If you want to scroll to the top including the headline, simply grab the parent again and use its offset instead.
This line:
$('body,html').animate({scrollTop: $(this).offset().top},200);
becomes:
$('body,html').animate({scrollTop: $(this).parent().offset().top},200);

How to Count Number of divs within another div

I saw that one can calculate the number of divs by id with the following code:
$('div[id^=d]').length
however I want to calculate the number of divs inside a in specific , example below
<div class="DAD">
<DIV CLASS="The DIV BE TOLD"></DIV>
<DIV CLASS="The DIV BE TOLD"></DIV>
<DIV CLASS="The DIV BE TOLD"></DIV>
<DIV CLASS="The DIV BE TOLD"></DIV>
</DIV>

$('div.DAD div').length would do it.
Or
$('div.DAD div.The.DIV.BE.TOLD').length
jsFiddle example
See: http://api.jquery.com/length/

JQuery allows you to use the syntax of CSS selectors (have a look here):
$('div.DAD div').length
should give the answer you're looking for

Selecting only one div of entire css class in jQuery

my goal is to show an overlay on a div when that div is hovered on. The normal div is called .circleBase.type1 and the overlay is circleBase.overlay. I have multiple of these divs on my page. When I hover over one .cirlceBase.type1, overlays show on every .circleBase.type1. How do I prevent this?
Here is some code:
HTML
<div class="circleBase type1">
<p class="hidetext">Lorem ipsum</p>
<hr size="10">
<strong class="gray hidetext">gdroel</strong>
</div>
<div class="circleBase overlay">
<p class="date">11/12/14</p>
</div>
and jQuery
$(document).ready(function(){
$('.overlay').hide();
$('.date').hide();
$(".circleBase.type1").mouseenter(function(){
$(".overlay").fadeIn("fast");
$('.date').show();
$('.hidetext').hide();
});
$(".overlay").mouseleave(function(){
$(this).fadeOut("fast");
$('.date').hide();
$('.hidetext').show();
});
});

Use $(this) to get current element reference and do like this:
$(".circleBase.type1").mouseenter(function(){
$(this).next(".overlay").fadeIn("fast");
$(this).next(".overlay").find('.date').show();
$(this).find('.hidetext').hide();
});
and:
$(".overlay").mouseleave(function(){
$(this).fadeOut("fast");
$(this).find('.date').hide();
$(this).prev(".circleBase").find('.hidetext').show();
});

usually when I want to target something specific you just give it an ID.
ID's play better in JavaScript than classes.
If you had a specific container, using the container as your starting point is a good route as well
$('#container').find('.something.type1').doSomething();
This is much more efficient for jquery, because it only searches .something.type1 inside of #container.

Well I'm not sure exactly what you're looking to do, but it looks like you want to replace content in some kind of circle with a hover text, but with a fade. To do that you'll have to add some CSS and it would be best to change your HTML structure too.
The HTML should look like this:
<div class="circleContainer">
<div class="circleBase">
<p>Lorem ipsum</p>
<hr>
<strong class="gray">gdroel</strong>
</div>
<div class="overlay" style="display: none;">
<p class="date">11/12/14</p>
</div>
</div>
so your js can look like this:
$(function(){
$(".circleContainer").mouseenter(function(){
$(this).find(".overlay")
$(this).find('.circleBase').hide();
});
$(".circleContainer").mouseleave(function(){
$(this).find('.circleBase').show();
$(this).find(".overlay").hide();
});
});
Here's a working solution that includes some CSS to make it nice. Try taking it out and running it, you'll see the problems right away.

Wrap several div with other div

I have several div as following:
<div id='id1'>blabla</div>
<div id='id2'>blabla</div>
<div id='id3'>blabla</div>
<div id='id4'>blabla</div>
<div id='id5'>blabla</div>
<div id='id6'>blabla</div>
And I would like to add a new div (<div id='newdiv'>) in order to wrap the div I specify.
For example before 'id3' and after 'id5'.
So we obtain:
<div id='id1'>blabla</div>
<div id='id2'>blabla</div>
<div id='newdiv'>
<div id='id3'>blabla</div>
<div id='id4'>blabla</div>
<div id='id5'>blabla</div>
</div>
<div id='id6'>blabla</div>
Do you know jQuery code to do this?

Use jQuery .wrapAll() :
$('#id3, #id4, #id5').wrapAll('<div id="newdiv" />')
Fiddle : http://jsfiddle.net/K4HVR/

Probably a simple plugin to make it more flexible, reusable:
$.fn.customWrap = function (end, wrapperDivAttr) {
this.nextUntil(end).next().addBack().add(this).wrapAll($('<div/>', wrapperDivAttr));
}
$('#id3').customWrap('#id5', { id: 'newDiv'}); // call the function on the startelement, specify the end elements selector and attribute obj.
nextUntil to get all the divs until the end div, then next to select the end div as well, and addback() to add the previous elements (nextUntil ones) to the collection and then add() to select the start div as well and then wrapAll of them.
Demo

In a bit of a hurry so this is untested but something like this?
$("#id3, #id4, #id5").wrapAll('<div id="newdiv" />');
EDIT: Oh damn, looks like Karl-André beat me to it!

HTML Paginated Two-Column layout

I have a two-column page (<p> tags after the first half are moved to column 2 with javascript).
My problem is that I want to break it up into "pages" like you'd see if you were reading a PDF.
Is there a neat way to do this? Or do I need to check if each page is overflowing programmatically as I fill them? Would that even work?

A possible way to do it is to make all different div's with all the copy in it and then with scrollTop go to the according page/collumn.
Something like:
<div id="page1" class="page">
<div id="p1_column_1" class="column">Here all the copy</div>
<div id="p1_column_2" class="column">Here all the copy</div>
</div>
<div id="page2" class="page">
<div id="p2_column_1" class="column">Here all the copy</div>
<div id="p2_column_2" class="column">Here all the copy</div>
</div>
Then css give it a height a width and overflow hidden and then with javascript/jquery something like:
var curr_col = 0;
var col_height = $('.column').height();
$('.column').each(function() {
$(this).scrollTop(col_height*curr_col);
curr_col++;
})
Edit
Check this fiddle to see the result: http://jsfiddle.net/taPjR/3/ .
In the example I copied the text with jQuery from the first div.
And I know it's very a dirty way, but I'm not sure if there is another keeping different fonts/font sizes and the images in the copy in mind.
Maybe a pdf generator like LaTex (http://www.latex-project.org/) could also be interesting?
Hope I could help.
