I'm not sure how to ask this question, so maybe that is why I can't find an answer to it, as well as being incredibly new to javascript in general, but here goes:

I'm trying to change the content of my main div using javascript by being able to click on a "link" that changes it. 
I THOUGHT I found a solution when I looked online with the

```
$( "#but2" ).click(function() {
   $("#Main").html("fffffffffffgdfg");

```

however when I try to add the content into the `html("")` section, if it has the `<div class=""></div>` in it at all, it ceases to function. It works fine if it's just text or stylized text, but I want to be able to change the insides all together since I am using stylized divs to create a cohesive webpage. I can understand if what I am asking is impossible in the way I am asking to do it, but is there a way to do it, period?

an example of what I am doing

```
<div class="Main">content
   <div class="sub">sub content</div>
</div>

```

where the "sub" content would be changed with the javascript when the accompanying button is pressed.

More simply put: have a main page, then click a button that says "blog", and then blog entries show up (however that blog has div properties within it), without changing the content outside of "Main". 

I apologize if I am not making any sense. Hopefully someone can help! If you need anymore information, please let me know. I am desperate for an answer and very, very new to javascript.

EDIT:  
Here is the actual code used and a massive example of what I am trying to do. It was originally just .html("wall of code"), but I also tried out append("wall of code"), as well as trying to use '' instead of ""  

```
<script type="text/javascript">
$( document ).ready(function() {

    $( "#but1" ).click(function() {
      $("#Main").append('<div class="ddd"><h2>Sector Chimera</h2>

As well as my actual divs, where they are all nestled within "container", and the content I want changed is nestled in "d2"

```
<div class="d2">
