How I hide a div when jquery show another div?

I want that when the click activate the element2 div, the element should disappear. And the element2 div should not appear at the beginning.
$(".toggle").click(function() {
$(".element2").toggle();
});
$(".close").click(function() {
$(".element2").hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="element">
Element 1
<div class="toggle">
toggle
</div>
<div class="element2">
Element 2
<div class="close">close Element 2</div>
</div>
</div>

Add display none to hide an element from the start:
<div class="element2" style="display:none">
The rest of your code appears to be doing what it's supposed to, unless I am misunderstanding "I want that when the click activate the element2 div, the element should disappear"... which is entirely possible.

In order to have element2 hidden at the beginning you need to either add a style tag or even better add a CSS file where you will keep all of your stylings in one place.
For style tag:
<div class="element2" style="display:none">
For CSS:
.element2 {
display: none;
}
Then for your code you are close. In order to make element hide, you need to change it to:
$(".toggle").click(function() {
$(".element2").show();
$(".element").hide();
});
$(".close").click(function() {
$(".element2").hide();
$(".element").show();
});
The HTML will need some changes to, this will make what I wrote work the way I believe you want it to:
<div class="element">
Element 1
<div class="toggle">
toggle
</div>
</div>
<div class="element2">
Element 2
<div class="close">close Element 2</div>
</div>

You should probably do something like this:
$(".toggle").click(function() {
$(this).parent().find(".element2").toggle();
});
$(".close").click(function() {
$(this).parent().hide(); // close the correct .element2
});
In CSS you need to:
.element2 {
display: none;
}

just $(".element2").hide(); hide it at start
$(function() {
$(".element2").hide();
$(".toggle").click(function() {
$(".element2").toggle();
});
$(".close").click(function() {
$(".element2").hide();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="element">Element 1
<div class="toggle">Toggle </div>
<div class="element2"> Element 2
<div class="close"> close</div>
</div>
</div>

HTML
<div class="element">
<div class="toggle"></div>
<div class="element2" style="display:none">
<div class="close"></div>
</div>
</div>
EXAMPLE CSS
.toggle
{
display:block;
width:20px;
height:20px;
margin-left:10px;
float:left;
background:green;
}
.element2{
display:block;
width:40px;
height:40px;
margin-left:10px;
float:left;
background:yellow;
}
.close{
display:block;
width:20px;
height:20px;
margin-left:10px;
float:right;
border:1px solid #000;
}
JQUERY
$(".toggle").click(function() {
$(".element2").toggle();
});
$(".close").click(function() {
$(".element2").css({"display":"none"});
});

How to change styling of a specific div onhover of another element when divs share an id

I have multiple rows with 3 divs per row. Each div consists of two rows; in the first row a picture is displayed, in the second row a description is shown. HTML is like this:
<div id="row">
<div id="block1">
<div id="block1-top"><a><img></a></div>
<div id="block1-bottom">Text here</div>
</div>
<div id="block2">
<div id="block2-top"><a><img></a></div>
<div id="block2-bottom">Text here</div>
</div>
<div id="block3">
<div id="block3-top"><a><img></a></div>
<div id="block3-bottom">Text here</div>
</div>
</div>
<div id="row">
<div id="block1">
<div id="block1-top"><a><img></a></div>
<div id="block1-bottom">Text here</div>
</div>
<div id="block2">
<div id="block2-top"><a><img></a></div>
<div id="block2-bottom">Text here</div>
</div>
<div id="block3">
<div id="block3-top"><a><img></a></div>
<div id="block3-bottom">Text here</div>
</div>
</div>
Some CSS:
#block1, #block2, #block3
{
width: 25%;
height: 150px;
display: inline-block;
vertical-align: top;
background-color: #FFFFFF;
border: 1px solid #154494;
}
#block1-bottom, #block2-bottom, #block3-bottom
{
color:#FFFFFF;
}
I want the color of the text in the bottom of the block to change to #FEB90D on hover of the parent div. So for example when hovering over block1, I want the text color of block1-bottom to change into #FEB90D. I found a script which does this for me:
$(function() {
$('#block1').hover(function() {
$('#block1-bottom').css('color', '#FEB90D');
}, function() {
// on mouseout, reset the background colour
$('#block1-bottom').css('color', '#FFFFFF');
});
});
However, this only works for the first block of the first row. I think this is because the id's of the 1st, 2nd and 3rd blocks have the same name and the script cannot figure out on which block to apply the script.
Does anyone have any thoughts on how to fix this, without changing all the divs id's? I have 11 rows in total so using separate names for each div is not really an option in my opinion. So basically, the scripts needs to change the color of the second child of the hovered div.

You shouldn't be using id for more than one element. Change those ids for classes and it will work.

It's better to do this with CSS
.block1 > .block1-bottom {
color: #FFFFFF;
}
.block1:hover > .block1-bottom {
color: #FEB90D;
}
<div class='block1'>
<p class='block1-top'>This is paragraph 1</p>
<p class='block1-bottom'>This is paragraph 2</p>
</div>
IDs should be unique anyways. If you do it in jQuery, it should look like this.
$(function() {
$('.block1').on("mouseover", function() {
$('.block1-bottom').css('color', '#FEB90D');
}).on("mouseout", function() {
$('.block1-bottom').css('color', '#FFFFFF');
});
});

Ids should be unique. So add necessary classes and use class selector. So code is similar to below
$('.row .box').hover(function() {
$(this).find(".boxbottom").css('color', '#FEB90D');
}, function() {
// on mouseout, reset the background colour
$(this).find(".boxbottom").css('color', '#FFFFFF');
});
Here is the demo https://jsfiddle.net/afnhjdjy/

After you clean up your duplicate IDs problem, you can do this without javascript at all:
<div class="row">
<div class="block">
<div class="block-top"><a><img></a></div>
<div class="block-bottom">Text here</div>
</div>
<div class="block">
<div class="block-top"><a><img></a></div>
<div class="block-bottom">Text here</div>
</div>
</div>
CSS:
.block:hover .block-bottom {color: #FEB90D}

According to this situation:
I want the color of the text in the bottom of the block to change to #FEB90D on hover of the parent div
You may simply use:
.block:hover .block-bottom{
color: #FEB90D;
}

Run JS by clicking a div element

Im working on a website that has a few different colored boxes made with divs, and I want to use them to open certain things. Whether it be music, photos, etc. Im using JS to generate a random number and use the number to choose which song to open, but I have no clue how to attach it to the div itself.
</head>
<body style="background-color:#FFF;">
<div id="center">
<div id="header">
<div id="title"><h1>welcom3 :-)</h1></div>
<div id="wrapper">
<div id="redbox">
</div>
<div id="6box">
</div>
<div id="bluebox">
</div>
<div id="greenbox">
</div>
<div id="yellowbox">
</div>
<div id="yellowboxmargin">
</div>
<div id="yellowboxmargin">
</div>
<div id="yellowboxmargin">
</div>
</div>
</div>
</body>
</html>

use jQuery
<div id="box1"></div>
<script>
$(document).ready(function() {
$("#box1").click(function(){
yourfunc();
}
})
</script>

If you need run js code without jquery, use this example.
In head:
<script>
function hello() {
// do something
}
</script>
In body:
<div onclick="hello()">Hello</div>

I would follow the advice of Buddhi Abeyratne and use jQuery. Of course, this is just a guess, but I would say that due to the nature of your project, it will make things easier for you.
jQuery has different methods to attach events to an alement. In this case, you can use the shortcut ".click()".
I leave you here a snippet:
function do_something_cool(box)
{
alert("I have code to make something awesome with " + box.attr("id"));
}
$(document).ready(function()
{
$("#wrapper div").click(function() { do_something_cool($(this)); });
});
body
{
background-color: #FFF;
}
.colored_box
{
height: 50px;
width: 50px;
margin: 5px;
}
#redbox
{
background-color: red;
}
#bluebox
{
background-color: blue;
}
#greenbox
{
background-color: green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div id="center">
<div id="header">
<div id="title"><h1>welcom3 :-)</h1></div>
<div id="wrapper">
<div id="redbox" class="colored_box"></div>
<div id="bluebox" class="colored_box"></div>
<div id="greenbox" class="colored_box"></div>
</div>
</div>
</div>
</body>
But if you decide to don't use jQuery, here you have the vanilla javascript:
window.onload = function()
{
var boxes = document.getElementById("wrapper").getElementsByTagName("div");
for (var i = 0; i < boxes.length; i++)
{
boxes[i].addEventListener("click", do_something_cool);
}
}
function do_something_cool(evt)
{
alert("I have code to make something awesome with " + evt.target.id);
}
Btw, I guess it is just a copy/paste thing, but you forgot to close one div.
Also, pay attention to how I have separated html, js and css in the snippet. You should avoid inline js and css.
Good luck!

Automatically Scrolling a webpage with animating div

I am making a web app. I have created 25 divs.
I have Used jquery fadeIn() by which divs are gradually made and displayed one after another on screen.
But problem is that when 25 divs have been created, scroll is created due to which first 4 divs can be seen but the remaining can't be seen until user scroll the page.
I want that as one by one div is created, the page should automatically scroll to the div recently created and so on this process should be continued until the last div is created.

You can use
$('html,body').scrollTop($(".answer.visible:last").offset().top);
$(function() {
$(".answer").hide();
$('#demo').click(function(e) {
var _div = $('.answer[style*="display: none"]:first');
if (_div.length) {
_div.fadeIn();
$('html,body').animate({
scrollTop: _div.offset().top
},
'slow');
} else {
$(this).text('Done..!');
}
});
});
#demo {
position: fixed;
bottom: 0px;
left: 0px;
}
.answer {
width: 100%;
height: 200px;
border: 1px solid black;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="demo">Click here</button>
<div class="answer">1</div>
<div class="answer">2</div>
<div class="answer">3</div>
<div class="answer">4</div>
<div class="answer">5</div>
<div class="answer">6</div>
<div class="answer">7</div>
<div class="answer">8</div>
<div class="answer">9</div>
<div class="answer">10</div>
<div class="answer">11</div>
<div class="answer">12</div>
<div class="answer">13</div>
<div class="answer">14</div>
<div class="answer">15</div>
<div class="answer">16</div>
<div class="answer">17</div>
<div class="answer">18</div>
<div class="answer">19</div>
<div class="answer">20</div>
<div class="answer">21</div>
<div class="answer">22</div>
<div class="answer">23</div>
<div class="answer">24</div>
<div class="answer">25</div>
I think this looks pretty cool when we use slideDown+scrollTop. Check fiddle
Documentations
To get the coordinates
http://api.jquery.com/offset/
Set vertical position of the scroll bar
https://api.jquery.com/scrollTop/
Set horizontal position of the scroll bar
https://api.jquery.com/scrollleft/

I found this link here
smooth auto scroll by using javascript
Using this you could create something like this here:
http://jsfiddle.net/mrc0sp5j/
The main point is, that you create a scrolling-function using
window.scrollBy or window.scrollTo
http://www.w3schools.com/jsref/met_win_scrollto.asp
With jQuery .last or .eq you can specify which element you want to scroll to
$(".mydivobjects").eq(x).position().top
Hope this helps

Muliple hidden fullscreen divs?

I'm working on my portfolio website, but can't solve the following problem.
The website is basically just pictures, if you click on one,
a semi-transparent fullscreen div opens with information (more pics and some text).
If you click again the div will close.
jQuery for hiding and showing:
<script>
$(function()
{
$('.masonryImage').click(function()
{
$('.hiddenDiv').show();
$("body").css("overflow", "hidden");
});
$('.hiddenDiv').click(function()
{
$('.hiddenDiv').hide();
$("body").css("overflow", "auto");
});
});
</script
HTML:
<div class="masonryImage">
<img src="images/pic1.jpg" alt="">
</div>
<div class="hiddenDiv">
<div class="text">
<p>Lorem ipsum...</p>
</div>
<div class="pics">
<img src="images/pic2.jpg" alt="">
</div>
</div>
So far it works with one picture, but when I'm adding another,
the new hidden text will overlay the first one, same with the pictures.
Is it because I'm using the same class ("masonryImage")?
Or isn't my Javascript removing the divs properly?
Many thanks.
Edit: CSS might be usefull:
.hiddenDiv {
position:fixed;
top:0;
left:0;
background:rgba(255,255,255,0.8);
z-index:900;
width:100%;
height:100%;
display:none;
overflow: scroll;
}
.masonryImage {
margin: 20px 20px 20px;
display: inline-block;
cursor: pointer;
}

here is how I modified your code :
DEMO
HTML
<div class="masonryImage">
<img src="..." alt="">
<div class="hiddenDiv">
<div class="text">
<p>Lorem ipsum...</p>
</div>
<div class="pics">
<img src="..." alt="">
</div>
</div>
</div>
I put the hiddenDiv inside the masonryImage so every masonryImage will have a custom hiddenDiv to show/hide.
JQUERY
$('.masonryImage').click(function()
{
if ($(this).find('.hiddenDiv').toggle().is(":visible")) {
//alert('hiddenDiv is visible !');
$("body").css("overflow", "hidden");
}
else {
//alert('hiddenDiv is hidden !');
$("body").css("overflow", "auto");
}
});
You can just use .toogle() to show/hide the div. $(this) refers to the clicked masonryImage and .find('.hiddenDiv') to its child (you can also use .children('.hiddenDiv') ).
Then you can test if the clicked div is hidden or visible with .is(":visible"), to apply your body custom css :)
Hope I helped you.
