I am new to developing Windows 8 store apps, and I am in the process of creating my first one.
The app I am making is a note taking app. I only started the app yesterday, so it's still very basic, but I am having a problem with the scrolling. Here is a screen shot displaying the problem:
As you can see, when a certain number of notes are entered, they start overlapping the screen. What I need to do is make it so that when the notes a certain amount of pixels from the side of the display, it makes it scroll-able.
The divs that the notes are contained in are created as the note is written. The notes also auto change size depending on the amount of text entered.
Does anyone know how I would make it so that they scroll to the left and right instead of overlapping?
EDIT:
Here is the CSS:
body {
overflow-x:auto;
}
#textInput {
padding:20px;
float:left;
margin-top: 20px;
margin-left: 20px;
position:fixed;
}
#noteInput {
display:block;
border-width:5px;
border-color:purple;
box-shadow: 5px 5px 5px;
}
#titleInput {
border-width:5px;
border-color:purple;
width:285px;
box-shadow: 5px 5px 5px;
}
#noteSubmit {
width:295px;
}
#headers {
margin-left:100px;
margin-top:80px;
}
#hr {
margin-right: 40px;
margin-left: 40px;
}
#noteContainer {
float:left;
margin-right:5px;
margin-top:5px;
margin-bottom:5px;
margin-left:400px;
}
I haven't really bothered with the UI and design much yet, as I want to get all the background stuff like javascript, jquery, and azure working first.
I am only doing this app as a project for practice, for the 70-481 and 70-482 exams I have in two months, so its never going to be in the store or anything.
Thanks for your help
Cheers

I strongly recommend using a WinJS.UI.ListView control instead of writing the div elements yourself.
That way you'll not only get a look & feel to your application that's consistent with what the user expects from a Windows 8 Modern UI app but it will also take care of the scrolling and management of the DOM elements for you.
See this tutorial on how to create and style a ListView control.
I agree with #ma_il, but if you do want to add scrolling functionality to custom elements, you simple wrap those elements in a div and add some CSS properties to that div...
overflow-x: auto; /* to scroll horizontally /
overflow-y: auto; / to scroll vertically /
overflow: auto; / to scroll in both directions */
If the contents of that div are wider (or taller or both) than the screen then your screen will automatically become scrolling and touch will be supported.

WebKit/Blink's (Safari/Chrome) default behaviour on MacOS since 10.7 (Mac OS X Lion) is to hide scroll bars from trackpad users when they're not in use. This can be confusing; the scroll bar is often the only visual cue that an element is scrollable.
Example (jsfiddle)
HTML
<div class="frame">
Foo<br />
Bar<br />
Baz<br />
Help I'm trapped in an HTML factory!
</div>
CSS
.frame {
overflow-y: auto;
border: 1px solid black;
height: 3em;
width: 10em;
line-height: 1em;
}

How can I force a scroll bar to always be displayed on a scrollable element in WebKit?
The appearance of the scroll bars can be controlled with WebKit's -webkit-scrollbar pseudo-elements [blog]. You can disable the default appearance and behaviour by setting -webkit-appearance [docs] to none.
Because you're removing the default style, you'll also need to specify the style yourself or the scroll bar will never show up. The following CSS recreates the appearance of the hiding scroll bars:
Example (jsfiddle)
CSS
.frame::-webkit-scrollbar {
-webkit-appearance: none;
}
.frame::-webkit-scrollbar:vertical {
width: 11px;
}
.frame::-webkit-scrollbar:horizontal {
height: 11px;
}
.frame::-webkit-scrollbar-thumb {
border-radius: 8px;
border: 2px solid white; /* should match background, can't be transparent */
background-color: rgba(0, 0, 0, .5);
}
.frame::-webkit-scrollbar-track {
background-color: #fff;
border-radius: 8px;
}

For a one-page web application where I add scrollable sections dynamically, I trigger OSX's scrollbars by programmatically scrolling one pixel down and back up:
// Plain JS:
var el = document.getElementById('scrollable-section');
el.scrollTop = 1;
el.scrollTop = 0;
// jQuery:
$('#scrollable-section').scrollTop(1).scrollTop(0);
This triggers the visual cue fading in and out.
Here is a shorter bit of code that reenables scroll bars across your entire website. I'm not sure if it's much different than the current most popular answer but here it is:
::-webkit-scrollbar {
-webkit-appearance: none;
width: 7px;
}
::-webkit-scrollbar-thumb {
border-radius: 4px;
background-color: rgba(0,0,0,.5);
box-shadow: 0 0 1px rgba(255,255,255,.5);
}

Browser scrollbars don't work at all on iPhone/iPad. At work we are using custom JavaScript scrollbars like jScrollPane to provide a consistent cross-browser UI: http://jscrollpane.kelvinluck.com/
It works very well for me - you can make some really beautiful custom scrollbars that fit the design of your site.
Another good way of dealing with Lion's hidden scroll bars is to display a prompt to scroll down. It doesn't work with small scroll areas such as text fields but well with large scroll areas and keeps the overall style of the site. One site doing this is http://versusio.com, just check this example page and wait 1.5 seconds to see the prompt:
http://versusio.com/en/samsung-galaxy-nexus-32gb-vs-apple-iphone-4s-64gb
The implementation isn't hard but you have to take care, that you don't display the prompt when the user has already scrolled.
You need jQuery + Underscore and
$(window).scroll
to check if the user already scrolled by himself,
_.delay()
to trigger a delay before you display the prompt -- the prompt shouldn't be to obtrusive
$('#prompt_div').fadeIn('slow')
to fade in your prompt and of course
$('#prompt_div').fadeOut('slow')
to fade out when the user scrolled after he saw the prompt
In addition, you can bind Google Analytics events to track user's scrolling behavior.
I am working on this site:
http://www.thecarlossanchez.com/Test/thecarlossanchez/Galleries/stilltest.html
When I created the thumbnails everything worked great, but for some reason it added all this extra space if you scrolled to the right. Everything worked the way it should with in the window and it never made me scroll right ever, so I ignored the extra space.
Now I am adding Isotope in order to filter the content, but when a category is selected all the thumbnails drop down and to the right. Something is centering the content to all that extra space. And I am not familiar enough with jquery to figure what where the problem is.
Here is an example of how it should work without isotope:
http://www.thecarlossanchez.com/Galleries/people.html
Any ideas on how to fix this?
Upon checking on your site, I noticed you got an enormous padding size being set on your gallery element.
Currently it's :
.gallery{
width:80%;
padding:800px; /* enormous padding */
position:relative;
}
I've changed that to padding: 0; and the extra space at the right side is removed.
.gallery should look like this now:
.gallery{
width:80%;
padding:0;
position:relative;
}
Also if you want to center your gallery when the page is resized, add margin: 0 auto to .gallery element.
e.g.
.gallery{
width:80%;
padding:0;
position:relative;
margin: 0 auto; /* center gallery */
}
Whenever i re-size my window the slider buttons (next/previous) disappear and do not move with the slider. Any idea on how to fix this?
JSFIDDLE:https://jsfiddle.net/b31kvqwr/
Buttons CSS:
#nav img {
position: absolute;
top: -10px;
cursor:pointer;
color:grey;
width:40px;
height:30px;
}
#prev {
margin-left: 530px;
font-size: 10px;
}
#next {
right: -30px;
margin-top: 13px;
}
PS: if the result in the jsfiddle doesn't show, expand the result tab.
This is how the slider looks like when full screen (the right way);
This what happens when i re-size the browser horizontally:
The buttons aren't moving with the slider. Any help please?
The problem at the moment is that you are using margin-left:530px; meaning that the arrows will always be 530px from the left of the screen no matter the size of the screen. It also looks like what ever is wrapping it has a set width and isn't resizing, your code was to messy for me to find this but there are a few thing that I found to make the problem a little better,
https://jsfiddle.net/b31kvqwr/2/
I have managed to keep it the correct place for a lot of the, however to improve get it working perfectly you will need to create 1-2 #mediaqueries to tweet the alignments at different sizes to make it perfect.
The way I did this was by changing margin-left to position:absolute and use a left positioning instead on your prev and next buttons;
#prev {
left: 50%;
font-size: 10px;
position:absolute;
}
#next {
margin-top: 13px;
left:58%;
position:absolute;
}
As I side note I would recommend cleaning up your code like #TingGaint said as it is insanely messy. Also when posting on stack try only include the relevant code not all of it as it makes it quicker and easier to look through and help.
EDIT
I have found the problem, still do what I said above however now instead of have the arrows div where they are now, move them out and so there below <div id="wrapper"> however you will have to play around with the placement as they will be at the top of the screen. However now they stay in the same place when re-sizing!

I am an awful web programmer trying to make a website for a school club. I'm using the fullcalendar plugin to display my Google calendar's events.
The trouble is, I'm using a lot of weird little tricks to get my sidebar to work, and I think that some of the css i'm using to get my divs to display in the proper places are preventing my calendar from displaying correctly. Right now, it's crammed at the top of my div (as you can see in the events tab). I just want the calendar to display beneath the header in my #events div.
I think the culprit lies somewhere in one of these css blocks:
.container div
{
opacity: 0;
position: absolute;
top: 0;
left: 0;
padding: 10px 40px;
overflow:hidden;
}
.container
{
font-family: Avant Garde,Avantgarde,Century Gothic,CenturyGothic,AppleGothic,sans-serif;
width:80%;
min-height: 100%;
left:20%;
background-color: #ffffff;
position: relative;
box-shadow: 0 -2px 3px -2px rgba(0,0,0,0.2), 0 2px 2px rgba(0,0,0,0.1);
border-radius: 0 3px 3px 3px;
overflow-x:hidden;
overflow-y:scroll;
}
I play around with the "position:absolute" in .container div, but that just makes all of my divs go haywire. I'm really, really new at this. If anyone can help me figure out why this isn't working or give me tips on how to manage my sidebar more intelligently, I would appreciate it.

Also, if any clarifications are needed, please ask. I hope I have given enough information.
I think I might have a sollution for you:
change
.container div {}
to
.container > div {}
What you're saying with .container div {}, is that ALL divs within the .container must have that style. This is apparently not what you want.
With .container > div, you only select the div's within the .container on the 1st level.
I.E.:
<div class="container">
<div> <!-- this div gets the styling from .container > div -->
<div> <!-- this div doesn't get styling from .container > div --> </div>
</div>
</div>
I hope I made this clear for you.
Give a height to your div, either in the HTML initially, or in the JavaScript when that populates the div with something. Since the page starts up with nothing much in the div it doesn't have any height. Later the JavaScript is adding content, but that won't change the height, so scroll bars appear instead and everything is out of sight. So give it enough height to hold all the content (use em units for the height, rather than px units, so it won't matter what text height your users are using).
Also check out your JavaScript syntax - there's an unwanted comma I think in the $(document.ready()) function, for instance, which should stop that bit of code running.
Also correct your HTML (run it through an HTML validator - there's several around). The errors aren't causing your particular problem, but needs cleaning up nevertheless. It needs a DOCTYPE eg for HTML5. The link to normalize.css should be in an href not an src attribute, and the for attributes in your labels don't all point to field names.
Having trouble getting my side spry menu to take up the length of the whole web page. I was thinking some like this
$("nav").css({
"height" : $("nav").height()
});
would maybe suffice in stretching out the side, but still no luck. I just want grey like in this jsfiddle http://jsfiddle.net/nLq9b/1/ to reach the bottom of the page regardless of the length.
thanks
Try this:
nav {
background: #666;
padding-top: 10em;
width: 10em;
position:absolute;
top:0;
bottom:0;
}
no jQuery needed.
