How to constrain rendered HTML code inside a div

I have a function that renders the HTML code from a textarea into a div of a certain size. The size of this div is determined when the page loads and is generally about 45% the width of the browser. I would like to know if there is any way to constrain what is rendered to not go out of the bounds of this div, but to instead add scrollbars if the rendered content exceeds the boundaries.
Basically, I'd like this div to behave like a browser window would when you render an HTML web page. Here is the code I have that does the rendering:
$(document).ready(function(){
$("#showmeImg").click(function(){
$("#outputContainer").html($(myEditor.getValue()));
});
});
So when 'showmeImg' is clicked, the contents of 'myEditor' is rendered and place within the 'outputContainer' div tag. All I have for this div tag are basic styling like background color, width, and height.

You should be able to get that effect using CSS. If you are setting the width programatically (as your question seems to suggest), then all you would need to do is set the height and overflow styles to get the desired behavior. Something like this:
#outputContainer {
height: 300px;
overflow: auto;
}
If you want the scrollbars to always be there (regardless of whether or not scrolling is needed for the current content), use overflow: scroll;.

You should add the CSS Rule 'overflow:auto' to the containing div. If the content spills outside of the div, scroll bars will be added automatically.

Have you tried something like this?
#outputContainer {
ovwerflow-y: auto;
}
This will add a vertical scrollbar, when there is enough content inside your container.
There are many nice jQuery plugins for adding nicer scrollbars though :).

Cannot position Google +1 button with CSS?

I'm having some trouble positioning the Google +1 button on my website. The div is as follows:
<div class="g-plusone"></div>
The CSS I'm using is pretty simple:
.g-plusone
{
position: absolute;
top:95px;
left:715px;
}
Despite what would seem straightforward, it simple does not want to move.
I know for a fact that the div in question is being accessed. What's strange is that other social sharing buttons, such as the FB like below follow the same syntax and are positioned perfectly.
.fb-like
{
position: absolute;
top:62px;
left:715px;
}
Adding !important to the values does nothing, unfortunately.
Any ideas?

When Google loads +1 button the .g-plusone class seems to disappear, so try to put this DIV inside another DIV, as illustrated below:
HTML:
<div class="google-button">
<div class="g-plusone"></div>
</div>
CSS:
.google-button
{
position: absolute;
top:95px;
left:715px;
}

After page loads, the Google div called g-plusone turns into a lot of code, but, you can manipulate this button with id generated.
In my case, for example, to align the button in the middle of the line I put:
#___plusone_0{
vertical-align: middle !important;
}
Note: The id ___plusone_0 is the id generated by the google codes. Do whatever you want with this id.

Use something like Firebug to ensure you're targeting the correct element. The +1 button is very deeply nested, so you'll most likely need to look further up the DOM tree to get to it's outermost wrapper. You will be able to set the position of that without needing to use !important or anything, so I would definitely check this first.
Sorry, I would have just added this as a comment above but I don't seem to be able :)

How to set a target="_blank" in a DIV tag?

Got a page that displays some buttons (background images, etc) and they are all clickable. What I want this specific button to do is open the target page in another browser tab using *target="_blank"*. The way it is setup as the href in a div I cannot do this. Any ideas on a work around for this?
<div class="dashboard_navbutton" href="Home/RequestRedirect" style="background-image: url('#Url.Content("~/Content/images/Form_button.png")');">
<p>Insert witty text here</p>
</div>

Just make that div an a and add display:block; to the style.
EDIT: Ensure that your chosen DOCTYPE supports the use of p inside an a element. More generally, it should use the computed style for display rather than the tag name to determine if an element is inline or block in terms of having one in the other. I believe the HTML5 one is fine: <!DOCTYPE html>.

trap the onclick event for the div, call a javascript function, have the function openthe window.
html snippet
onclick="opennewwin()"
function opennewwin(){
var awindow = window.open(loc, "blank", "height=500px,width=500px");
}

I was trying to dynamically add divs that would also function as links.
This was my solution using CSS.
First the container needs relative positioning.
.container {position: relative;}
Next, the link needs to fill the container.
.container a {position: absolute; width: 100%; height: 100%; top: 0; left: 0;}
Like I said, I dynamically assembled the div, but the html would look something like this:
<div class='container'>[some other content]</div>
The container must be position relative, otherwise the position absolute link fills its first position relative ancestor (probably the whole viewport).
Of course, you can add styling to the div or the link. Note, I was using a position: sticky nav-bar, and I had to set it's z-index high in order to avoid collisions with the div buttons.
Pros: whatever styling and targeting you set for your links will apply. Good 'style': doesn't put a block element inside an inline (should avoid browser issues, though I haven't thoroughly tested it). Does not require any other languages or frameworks.
Cons: Not as simple as Niet's answer, but shouldn't be Doctype dependent.

adjusting height of div based on internal div

I have a set of divs like so:
<div id="textArea">
<div id="text"></div>
</div>
CSS properties:
#textArea {
height: auto !important;
min-height: 2em;
overflow: hidden;
}
#text{
display: none;
}
I'm filling in the div with the id of "text" with error messages coming back from a POST request using jQuery. The size of the data coming back is not static, but my problem is that the div is not adjusting.
I am basically trying to mimic the Ruby on Rails default flash message that will push divs further down the page with a dynamically adjusted div.

I think you are simply doing too much - A div should automatically expand to fit the text content inside it, unless you have a specific rule saying otherwise. Do you have a rule that specifies a height for all divs? Is that why you have the height: auto !important here? Are you using a reset stylesheet? Something external to these rules is affecting your divs.
Hope that this points you the right way.

Div's should update height and width automatically unless otherwise told to. What is your jQuery code to update the div? What are you using to reveal the div to the browser (since it's currently set to display:none)? Have you tried using firebug to inspect the elements?

jQuery toggle changes element's width? I don't want it to

I currently have a table that has a width of 94%, and the following toggle set to it:
$(document).ready(function(){
$("#moreinfo").hide();
$("#toggleinfo").click(function () {
$("#moreinfo").toggle('normal');
});
});
It toggles fine, but as soon as you toggle, the width goes really small and I have no idea why. If I remove the hide() it's the right width, but again as soon as I start toggling it, the width automatically resizes.
Just tried the following CSS too:
#moreinfo { width: 94% !IMPORTANT; }
Edit: it seems to completely remove any width applied through CSS when I toggle it
Edit2: Wrapping it inside another div works! Not ideal, but not a bad solution I guess.
Any way to stop this please?

The jQuery toggle() function sets your target element ('#moreinfo' in this case) to display: block. It's just a guess without seeing your CSS or HTML, but I'm picking that the table, when having its display property changed, is being positioned or laid out incorrectly.
You may be able to work around this by wrapping your moreinfo element in another div with display: inline or position: relative? But that's just a guess. Do different browsers show the same result?
