HTML code flows off page?

So I have this HTML code, it displays a twitter feed.. The only problem is, it flows off the page. I would like the feed to be 100% width and 600px height. I've fiddled with this for a while, and can make it work somewhat.. I think it needs to be one single code.
https://jsfiddle.net/33nw5jcd
<div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js">
</script>
<script>
appreplicaapp = 'twitter';
appreplicaapikey = 'aa869d1f61a088e04e6fe1a66fc07933e404f9bb';
</script>
<script src="//api.appreplica.com/js/1/arc.js"></script>
</div>

Try this:
CSS
#a {
height: 600px;
background-color: #fff;
width: 100%;
}
#a::after {
content: 'hello this is the last node';
}
HTML
<div id="a">
</div>
Note: Try keeping your script after the element with id a. It may be a issue where your script executes before your element is rendered.

jquery slideDown, slideUp wiggling

I am new to jquery and have problem with one part of my script. basically I am making dropdown div when mouse is over the button, but div starts moving up and down like crazy. here is what i have done: `
<script type="text/javascript">
public var boolean opened = false;
$("#drop1").slideUp();
$("#first").mouseover(function(){
$("#drop1").slideDown();
});
$("#first").mouseout(function(){
$("#drop1").slideUp();
});
});
also I tried using boolean variable but it gives me error.
<script type="text/javascript">
$(document).ready(function(){
public var boolean opened = false;
$("#drop1").slideUp();
$("#first").mouseover(function(){
if(!opened){
$("#drop1").slideDown();
opened = true;
}
});
$("#first").mouseout(function(){
if(opened){
$("#drop1").slideUp();
opened = false;
}
});
});
here is HTML if you want, but I think there is everything ok.
<link rel="stylesheet" type="text/css" href="design.css">
<div id="first" style="position: absolute; left: 0px;">
<a class="btn" href = "TheShooter/Launcher.exe" ><b>LAN shooter project</b></a>
<div id="drop1">
<em>shooter project main page</em> <br/>
info: Local Area Network multiplayer game, made with unity. Project not finished yet, but sometimes fun to play. <br/>
controls: walking: w,a,s,d<br/>
shoot: LMB.<br/>
zoom: RMB.
</div>
</div>
Thanks for any help.

So it looks like you might be more used to strongly typed languages like C#. JavaScript and its library jQuery are loosely typed, meaning you don't declare scope or type. Here's your code above cleaned up a bit to use correct syntax and solve the issues you're seeing:
$(document).ready(function(){
var opened = false;
// Instead of sliding this up, give the #drop1 element
// a property of display: none; to start - then remove the line below
$("#drop1").slideUp();
$("#first").mouseover(function(){
if(!opened){
// Below, I'm using a callback, which means the boolean
// won't update to true until after the animation is finished
$("#drop1").slideDown(400, function() {
opened = true;
});
}
})// Since it's the same element, we can chain events
.mouseout(function(){
if(opened){
// Another callback
$("#drop1").slideUp(400, function() {
opened = false;
});
}
}
});
});
Let me know if you have any questions about the above!

Hi please refer this fiddle which should answer your question. No need to add any boolean or conditional checking:
<div id="wrap">
<div id="text">text</div>
<div id="video">video</div>
and js
$(document).ready(function(){
$("#wrap").mouseover(function(){
$("#video").stop().slideDown("slow");
});
$("#wrap").mouseout(function(){
$("#video").slideUp("slow");
});
});
and css
#text
{
margin-top:20px;
float:center;
font:VNF-Museo;
font-size:40px;
color: #333;
margin-left:auto;
margin-right:auto;
border: 1px solid #000;
}
#video
{
display:none;
width:1024px;
height:278px;
border: 1px solid #000;
}

I think you should try something like this:
$(document).ready(function() {
$("#first").mouseover(function(){
$("#drop1").slideDown("slow");
});
$("#first").mouseout(function(){
$("#drop1").slideUp("slow");
});
});
See this example above, from the jQuery offical documentation, for more information:
http://api.jquery.com/mouseover/
http://api.jquery.com/mouseout/

Here is one more answer with live example,
$(document).ready(function(){
$("#drop1").mouseover(function(){
$("#first").slideDown("slow");
});
$("#drop1").mouseout(function(){
$("#first").slideUp("slow");
});
});
#first, #drop1 {
padding: 5px;
text-align: center;
background-color: #acacac;
border: solid 1px #c3c3c3;
}
#first {
padding: 50px;
display: none;
background-color: skyblue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<div id="drop1">Mouse over on panel to slide down</div>
<div id="first">Hello Stackoverflow ..!</div>

Using toggleClass in jQuery to shrink a div

I have a div and I'm trying to shrink it when I click a button. And when I click it again, I want it back to the original size. I'm using toggleClass for this, but I did something wrong with my code, and I'm not sure where. Please take a look. Thanks.
//*********************************************************************
<style>
div {
border: 1px solid black;
width: 500px;
height: 500px;
}
.shrink {
width: 250px;
height: 250px;
}
</style>
//*********************************************************************
<button type = "button"> click me </button>
<div> Can you tell me a secret? </div>
//*********************************************************************
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type = "text/javascript">
$(document).ready($function {
$("button").click(function(){
$("div").toggleClass("shrink");
});
});
</script>
//*********************************************************************

It's kind of a typo. You wrote "$function {" but you probably mean this:
$(document).ready(function() {
The rest is fine.
Also, document ready can be expressed in a shorter form:
$(function() {
...
...
});
Maybe you just confused those two. I did a few times too, back in my beginner days :)

Here: the jQuery ready method takes an anonymous function as an argument... so te problem with your code was only to pass that function function(){}
Here you can see the code in action: http://jsfiddle.net/leojavier/41wmck17/
$(document).ready(function() {
$("button").click(function(){
$("div").toggleClass("shrink");
});
});

How to toggle two images onClick

I'm making a collapsible treeView.
I made it all, I just need my + and - icons to toggle whenever they are clicked.
I did the part when I change an icon from + to -, on click, with jQuery with the following code:
$(this).attr('src','../images/expand.gif');
Problem is, I don't know how to make it go other way around, when i click on the node again :)

This should work:
<style>
.expand{
content:url("http://site.com/expand.gif");
}
.collapse{
content:url("http://site.com/collapse.gif");
}
</style>
<img class="expand">
<script>
//onclick code
$('img.expand').toggleClass('collapse');
</script>

Look for jquery function toggleClass :)
http://jsfiddle.net/Ceptu/
Html:
<div id="box">
Hello :D
</div>
Jquery:
$("#box").click(function () {
$(this).toggleClass("red");
});
Css:
#box {
width: 200px;
height: 200px;
background-color: blue;
}
.red {
background-color: red !important;
}
Remember that !important is realy important!!!
Lots of ways to do this :D

I wanted to do this without making classes. Inside your click event function, you could do something like this:
if($(this).attr('src') == '../images/collapse.gif')
$(this).attr('src', '../images/expand.gif');
else
$(this).attr('src', '../images/collapse.gif');

add plus as a default img src then define a minus-class to change the image source to minus image
$("selector_for_your_link").click(function () {
$(this).toggleClass("minus-class");
});

Jquery text toggle

I am trying to make a jquery text toggle. If you rollover the element, the text appears next to it and vice versa, it dissappears when you leave the element area.
My code does not work yet. Also, i would like to include different texts for different links. If there is a simpler way please suggest.
HTML
<div id="container"></div>
clickclickclick
JS
$("#ovr").mouseenter(function() {
$(#container).html("wazaap");
}).mouseleave(function() {
$(#container).html();
});

You are forgetting the quotes in the jQuery selector:
$("#ovr").mouseenter(function() {
$("#container").html("wazaap");
}).mouseleave(function() {
$("#container").html("");
});
Edit
If you want different sentences, you can do this:
JS
var description=new Array();
description["one"]="Here comes the first";
description["two"]="And here the second";
description["three"]="Now let's have the third";
description["four"]="Finally the last one, fourth";
$("a.link").mouseenter(function(){
$("span#description").text(description[$(this).attr("id")]);
}).mouseleave(function(){
$("span#description").text("");
})​
HTML
one
two
three
four
<span id="description"></span>​
Check working here

Try to do it with hover() function. Code will be cleaner.
Basic example:
jQuery:
$("#container").hover(
function() {
$('.cText').text("click");
},
function() {
$('.cText').text("");
});
CSS:
#container {
position: relative;
background-color: #EEEEEE;
width: 100px;
height: 100px;
position: relative;
display: block;
}
HTML:
div id="container"></div><span class="cText"></span>
Regards

Update
Base on OP's comments wanting to use several links to show text I tried this:
http://jsfiddle.net/cZCRh/4/
It doesn't quite work with a class because all links get the same text
This works http://jsfiddle.net/cZCRh/1/
<div id="container"></div>
clickclickclick
$("#ovr").mouseenter(function() {
$('#container").html("wazaap");
}).mouseleave(function() {
$("#container").html("");
});
​
The problem was the mouseleave was in the wrong place as well as missing quotes around the element IDs
