I have a seemingly basic question that I can't find any resources in what I am trying to acheive. I'm new to JavaScript and fairly mediocre at CSS.
What I am trying to accomplish is this. A page which can be displayed on a TV screen showing a list of sports results, overflowing to the right. I want the page to automatically scroll that div across to the right (which has a dynamic length depending on the amount of content) so it can see all the scores across all divisions and automaticaly scroll content to the right. When it reaches the end, pause, and then refresh (using Ajax) snapping back to the beginning.
I'm sure if I can be pointed in the direction of the right functions to use I can hook the various parts together.
Here's an example of something I am trying to run on page load that I'd like to scroll smoothly to the end over the course of 10 seconds, I just can't work out how to identify/set the "end" of the div.
$('#ScrollMe').animate({
scrollX: ??? //To div end;
}, 10000);
I think if I can solve this part, I can solve the rest.
Any pointers? Javascript, CSS.... open to anything!
You can use the .scrollWidth property to determine how far to scroll, subtracting the visible width will give a more accurate end point, eg:
(styles and animation time set to 2s, just to demonstrate what's happening)
$("#scrollMe").animate({
scrollLeft: ($("#scrollMe")[0].scrollWidth - $("#scrollMe").width()) + "px"
}, 2000);
#scrollMe { width: 100%; border:1px solid blue; overflow:auto; }
#inner { width: 6000px; border:5px solid red; height:20px; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id=scrollMe>
<div id=inner>
</div>
</div>
You just need to apply overflow: scroll css propertie, to the div you want to "overflow" the page width. So it will add a bar below the div, such as the default scrolling bar of every browser.
parentDivWithContentToOverflow{
Overflow: scroll;
}
This is a great example of what you need.
https://css-tricks.com/snippets/jquery/smooth-scrolling/
But you need to specify the div to achieve this.
If your requirement is only to scroll to the end of the page(which is right), then you can use your example. But you need to specify the pixel location to scroll to right. For that, you might need something like the below.
function getWidth(){
return Math.max(document.body.scrollWidth,
document.documentElement.scrollWidth,
document.body.offsetWidth,
document.documentElement.offsetWidth,
document.documentElement.clientWidth);
}

Here's my website:

What I'd like to do is have multiple veritcal and horizontal scrolls on the page. I think I should do this with Jquery.
Vertical:
Writing link at the top would scroll down when clicked so that the writing section on the side bar is at the top of the page.
Contact link at the top ā same thing
(When I get the hang of this, Iām going to add up and down arrows on either side of the elements in the sidebar to scroll up and down to next / previous element. )
Horizontal:
In the writing section on the sidebar, Iād like the deadspin, gawker, and the awl links to scroll to content within the writing box when those buttons are clicked. I imagine this would have an overflow:hidden element somewhere? If vertical scrolling within this box would be easier, thatās ok too.
I found this excellent site which I think will be helpful:
http://demos.flesler.com/jquery/scrollTo/
relative position and relative selector look promising.
I'm guessing that I make each button a link that will be able to scroll to another part of the page.
So I would this class selector (the contact nav bar at the top), for example:
.nav_box_r {
display: block;
float:left;
width:219px;
text-align: left;
padding-right: 40px;
padding-top: 169px;
margin-top: 0;
}
as a link to scroll to the bottom of the page to the contact info, like
$(...).scrollTo( 0, 800, {queue:true} );
(Secondary question: Should I redo all the statis elements to have fixed positions?)
I'm new to this so would appreciate specificity. (Does the script go in the head, are the scrollUp / down to relative or fixed positions, etc.)
Thank you!
Hopefully this helps, you can use a href to jump to divs within your website.

How can I scroll to a specific location on the page using jquery?
Try this code
$(".yourclass").click(function() {
$(this).animate({ scrollTop: $('#title1').offset().top }, 1000);
});
Have a look at Balupton's ScrollTo plugin, it might be easier for you + there's a demo in there that shows you how to set it up.

I have a div called calendar that is inside a div called cal-container. The calendar has width:100% so currently it takes up the whole cal-container.
I need to add a side-panel div. This div will have a fixed width of 150 pixels. Thus, #calendar width should be #cal-container width - 150px. Is this possible with CSS or am I forced to use a table?
If it is possible, is there an example? I googled it but nothing like what I want came up.
The side-panel can be hidden and shown by click a button so adding padding will not work.
Here is an idea of what I mean:
The days part is #calendar, and the Unscheduled part is the side panel of 150px.
I tried floating the calendar left, and cloating the side panel right and giving it a width of 150px. But the idea is if I hide that div, the calendar should then take 100%.
Thanks
Like this, the blue would be side and calendar be the left, but calendar needs to take up the room side does not when hidden.

Result of float:
Got a working solution for you here.
The code to get this working basically hinges on the following structure:
<div class="sideBar">
...
</div>
<div class="tableWrapper">
<table>
...
</table>
</div>
Next, make sure the elements have these significant CSS properties:
.sideBar {
float: right;
}
.tableWrapper {
overflow: hidden;
}
table {
width: 100%;
}
What's happening here is that the .sideBar floats right, and takes up whatever space it needs to. Meanwhile, the .tableWrapper will take up whatever space is left by virtue of overflow: hidden. Finally, tell the table to take up 100% of its available width.
Click the button in the demo to see the table automatically resize.
All major browsers and IE10 support flexbox. Not supported < IE10.
I'm recently facing a dilemma with my new Wordpress site.
I'm wondering how to keep a part of my header image visible when i'm scrolling down in the page.
For now, my header image is 75% of the page height, but when i'm scrolling down, the image disapear as it should be.
But what i want, is that a certain part of it, let's say 20%, stay visible at the top in a "fixed" position.
So, to resume in pictures :
What i have without scrolling :

What i would like to have when scrolling down :

I don't know if i'm clear enough, though, thanks to everyone who will try to help me on this !
You can use a jquery plugin like sticky:
<div class="top">Content</div>
<div class="header"></div>
<div class="content">
....
</div>
Then for CSS, you apply your image:
.header
{
background-image: url('http://placekitten.com/200/300');
height:300px;
width: 100%;
}
Then in your js, you can use the sticky plugin:
$(".header").sticky({topSpacing:-250});
Notice the negative number on the spacing offset, which allows most of the image to be scrolled.
Example fiddle: http://jsfiddle.net/CZYav/2/
I have a demo here: http://jsbin.com/ubolos/1/edit
Just keep tracking you scrolled distance and modify the background property of the div when you find that user has scroll too far down. No other plugins of jQuery needed.
I have 2 toolbars, 1 of each side of the screen, and a main content area. I dont want it to have to sidescroll cause that is pathetic, so i was trying to figure out if someone could help me set it up.
My current attemp was:
$("#main").css("width", window.outerWidth - $("#t1").width() - $("#t2").width());
The issue is that it is too big still because of margins. Instead of me doing width, should i do outerWidth, similar to how i did window, or is there a jquery command which will do just that?
Thanks
here is a basic fiddle: it is set up differently, but the idea is there. I just am unsure as to how to do it. http://jsfiddle.net/fallenreaper/DfZx7/
Upon tinkering deeper and deeper with my fiddle, i am fairly certain i figured it out in the example i had given. derp Standby while i look and see if i can apply the same thing to my code.
The sample did not work with my code, but border was set to 2px around, for both main and attributes. Deducting 8 pixels resolves.
You don't need JavaScript to avoid scrollbars. It's a layout width two fixed-width columns and a liquid one.
Here is the "skeleton" of your layout in a responsive way:
<div id="window">
<div id="column-sx"></div>
<div id="main"></div>
<div id="column-dx"></div>
</div>ā
CSS:
#window {
width:100%;
overflow:hidden;
}
#column-sx {
width:54px;
float:left;
}
#column-dx {
width: 140px;
float:right;
}
#main {
width:100%;
float:left;
margin-right:-194px; /* left + right col width */
}
#main > * {
margin-right:194px; /* left + right col width */
}
This way it will never "break" nor cause an horizontal scrollbar.
Anyway, probably you want to set a min-width for #main contents, and add another container for contents instead of targeting them with > *
Check this fiddle with your code revised
Off the top of my head, i would think outerWidth would work. If it doesnt, you can find the margin value via the .style attribute - but thats not ideal.
One thing you should be aware of is window resize if your setting your widths dynamically and you truely hate horizontal scrolling. You could put the above function also in the $().resize() function to ensure the widths are always within the window and complement this with css min-width so it doesnt go too small.
I've been working on my new portfolio/website and decided to go for a design that is basically one big index page that scrolls horizontally to show the different sections and vertically to show the content of the sections. Both the container and the boxed inside have a fixed width. The container is positioned relative and the boxes inside are floated left and positioned relative.
My question now is - how do I make it so that, regardless of the size of the browser window the user has when opening the website and even when re-sizing, the first box appears centered horizontally in the browser window AND without revealing the content that is on its right (content to which the user can scroll horizontally using buttons)?
The inspiration for my website came from this website http://www.cosstores.com/
I've inspected the code and I believe they are doing it using JavaScript and negative margins; but my Javascript knowledge is quite basic and I don't really understand how these negative margins are implemented effectively.
Would appreciate it if someone could explain how it works for the COS website or even come up with an easier alternative a noobie like me could use.
Thank you and please feel free to ask me to post anything else you think could help understand the problem better!
This is really quite simple, don't you worry. See it in action!
You'll need to work on a grid system. (You can use different-sized columns, but it's simpler if everything's nice and square.) Create a container div and a bunch of child "box" divs in your HTML:
<div id="container">
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
<br />
<div class="box"></div>
<div class="box "></div>
<div class="box"></div>
<div class="box"></div>
</div>
Use <br /> to start a new row. Otherwise, rows will extend infinitely. The container div is exactly the height and width of one box, so it will only show one box at a time. But you can scroll, obviously.
Annotated CSS below:
#container {
font-size: 0; /* remove gaps between boxes */
height: 400px; /* show one box at a time */
margin: 0 auto; /* center horizontally */
overflow: scroll; /* show scroll bars */
width: 400px; /* show one box at a time */
white-space: nowrap; /* let boxes continue horizontally until manually <br />'d */
}
.box {
display: inline-block; /* stack up left to right */
font-size: 14px; /* undo font-size from parent so you can actually see text */
height: 400px;
vertical-align: top; /* line up tops of boxes within row */
width: 400px;
}
Then, to scroll to a location with Javascript:
$("#container").animate({ scrollTop: 400, scrollLeft: 800 }, "slow"); //with animation
$("#container").scrollTop(400).scrollLeft(800); //without animation
You'll need jQuery to use that code. Well worth it, since it hides browser inconsistencies in scrolling with Javascript.
If you want to use the browser's scrollbars, you'll need to use the body as your container. It's trickier, because you don't have a specified width and height. There is no way to hide elements (for sure) from every userāsome have truly massive screen resolutions.
Basically, add a margin on each box so you get some space around it. With some quick JS calculations, you can figure out the location of each box and center it on screen. See updated fiddle.
Here's the relevant JS for anyone interested:
$("#scroll").click(function() { scrollCenter("#target"); });
scrollCenter("#home", 0);
function scrollCenter(target, duration) {
if (duration == undefined) duration = "slow";
target = $(target);
var offset = target.offset();
var top = offset.top - ($(window).height() - target.height()) / 2;
var left = offset.left - ($(window).width() - target.width()) / 2;
$("html, body").animate({ scrollTop: top, scrollLeft: left }, duration);
}
Run that OnDOMReady. The call to scrollCenter("#home", 0) forces the page to center the first box on load. You shouldn't even notice the jump.
Happy coding!
you should use the jQuery plugin scrollTo
http://archive.plugins.jquery.com/project/ScrollTo
Centering a div tag on the screen is easy. Set the margin property in it's css class to this:
margin:0px auto;
As for the rest of your question, this is a case for jQuery (in my opinion). Take a look at this link:
http://addyosmani.com/blog/building-spas-jquerys-best-friends/
And also google jQuery tutorials (you need to learn the framework first) and then, more specifically, "single-page sites" and "jQuery Paralax".
Good Luck!
