What is a good way of getting stacked progress bars to animate smoothly without flickering?
I'm currently using Bootstrap, changing the width styles (using Knockout).
Example: https://jsbin.com/lewuzewupo/2/edit?html,console,output
My problem is, if you watch that long enough, the green bar on the right flickers. This is seemingly because the animations cause it to get pushed to the right when the middle dark blue bar appears and disappears.
(I have tried everything I can think of to ensure that at no point in time do the total of the stacked bars exceed 100. If I stop using the progress-bar class and use my own that results in a similar look, but with no animation, then there is zero flickering and the bars are stable, always totalling 100.)
So is there a workaround for the problem in Bootstrap, or an alternative way of creating stacked progress bars that look as nice as the Bootstrap ones and animate smoothly?
[edit: added debugging to prove my percentages always total 100]
I think I've come across this kind of thing before - it's down to the 'complete' text. Basically it's not working out the widths quite right. 2 ideas.
Remove the 'complete' text and it should be ok.
Attempt to only display complete after a certain time and the values have dropped to a particular ratio.
Sorry can't be of more help.

I found a carousel (https://codepen.io/paulnoble/pen/yVyQxv) that has some awesome transitions and thought it'd be nice to integrate into a project I'm working on: https://joshrodg.com/halloffame/
My code is here: https://codepen.io/joshrodgers/pen/MWBPXBx
The responsiveness of the design needed to be adjusted slightly because to me having the content split (left, right) doesn't quite work that well on smaller screens (like phones) - it'd make it almost impossible to read. So, my idea was just to remove the right-side content all together.
I have that working and it looks exactly as I expect, except one thing...
Basically, there is vertical paging on the right-side of the slideshow. When you click on the next circle it rotates forward to the next slide, when you click on the previous circle, it rotates backwards to the previous slide. On a desktop screen (larger than 900px) the paging area stays on top of the rotating images, which makes the slideshow rotation look really nice. On my iPhone, and I'm guessing on other small screens, the rotating images appear to rotate on top of the paging area and then it re-appears.
I'm sure this is a simple tweak, but is there a way to keep the paging area on top while rotating through the images on a desktop and smaller screen like an iPhone?
This is also an issue on the original carousel, so I'm not sure how to fix it.
The paging area does have a z-index: 1 but for some reason the images still rotate on top of the paging area. I even tried setting it higher: z-index: 1000, but that didn't seem to do anything.
Anyone have any ideas?
Thanks

After looking into this a little more, I was able to find a solution!
My carousel__control div is what was controlling the vertical pagination, this was in carousel container and rightfully so, as it was controlling the position of everything inside. However, this also caused the issues I described, not really sure why.
All I did to fix this was move carousel__control out of the carousel container - basically right above it in the document. Then had to set my margins to match and adjust it's position. I couldn't keep the margin: auto and top: 0. Once I adjusted those two properties, everything started working as expected.

I have a hexagon menu on this site which is correctly working in chrome but it has rendering issues in FF and IE.
http://wrausch.de.w013b68e.kasserver.com/
When you hover the hexagon menu in FF/IE you can see 2 blue lines which are not fully covered by the hovereffect.
Since I just got the site from a colleague who left I don't know where to begin.
Any help would be appreciated.
Thanks
Transformed elements - like the skewed elements you used to create the hexagons - end up in positions that are measured in fractions of a pixel, and so the browser has to make a judgment about how to display elements on a screen where mathematically perfect shapes need to be represented in a grid of blocky pixels.
Two transparent elements are next to each other and are slightly overlapping due to this rounding. Since the elements are slightly transparent, any overlapping would show up as a dark line.
Mathmatically, the elements are not touching, but due to the expression and simplifications of the browser, they are now slightly overlapping.
On Firefox the lines appear only when the transition is complete. This occurs because the rendering engine behaves differently during an animation than when it is complete.
To fix this I would try using fully opaque background colors when the user hovers. That way even dramatic overlapping would not cause a change in color.
Dear Elders of The Internet -
I have created a headache for myself, and I hope you can help :-)
This is a two-part questions. I have a page with three panels, and want a horisontal slide. For this I have created buttons, see live demo here.
1. Horizontal slide, responsive
When clicking top right button "two right panes" I want the page to show just that: the two right panes only. This is not a problem on large screens, but I cannot get it to work on slightly smaller (media queries and further responsiveness, I think I will be able to figure out).
Similarly; when clicking "single left pane" I would like it to stretch the third (far right) panel, and hide the two others.
Clearly, I want it to respond to a 100% viewport.
2. Highchart
I cannot get the Highchart chart to act accordingly depending on the top left buttons sliding. The highchart will adjust if I resize the whole window, but I cannot get it to adjust when sliding panels. For a demo of a chart that works, scroll down in third panel (this is "homemade" graphs).
I have attempted to illustrate the problem in the screenshots below.
(I have posted another question relating to the same page, if you should be so inclined to take a look).
I suspect it is pretty simple, but I cannot for the life of me see where I went wrong. Any hints would be much appreciated. All the best.
Highcharts will resize only when window is resized, if you want to resize chart use chart.setSize(w,h), see reference.
Well, good people, I kinda figured it out myself... for the possible benefit of others; my solution was to set the width of the two first columns fixed (or rather; max-width), and thereby using calc to calculate the size of the third columns with minus the two fixed width divs.
width: -webkit-calc(98% - 520px);
width: calc(98% - 520px);
For the Highchart part of the question, much thanks to #Pawel for prompt answer. I haven´t entirely worked it out, as we are currently discussing whether using Highcharts or not is the way to go. If so, I guess I might be back with more questions later.
I've been trying to do something like this for quite a bit, and have tried a variety of methods from fake scroll bars and DOM-tricking code. Nothing seems to quite be as clean / functioning as I need it to be.
What I'm trying to do is have a horizontally scrolling div (with scrollbar), with a vertically scrolling div nested within it. Ideally the single horizontal scrollbar would scroll, and after a certain point--vertically scroll the "go-up" div next to it.
Here's an example diagram for those who need to visualize:
I think I have a solution that could work:
Basically I'm thinking that the horizontal "scene" could have overflow that equals the height of the "go-up" div. And after the horizontal width of the "scene" passes...you can, onScroll, shift the "go-up" container right using (ScrollLeft) and up using (ScrollTop).
Basically giving you the illusion of controlling it's vertical scroll with a horizontal scrollbar.
Check out the code here: http://jsfiddle.net/jPzqj/1/
I know how to pass a function at the end of the "scene"...currently I'm using:
$('#main').scroll(function(e)
{
if($(this).scrollLeft()>1430)
{
}
});
My only issue is I'm not quite sure how to approach the math that would allow me to shift the go-up container. How do I pass in the "scene" divs scroll value into the ScrollLeft and ScrollTop values of "go-up"...
Could anyone give me any advice on this at all?
Thanks.
You are totally off the right path, no vertical scrollbars are involved.
That is a good site (not the one that you make in 30 minute obviously), and the javascript is obfuscated, but if you are interested, you could watch the source with Firebug to understand what's going on.
It works by mixing a javascript library, some cool CSS3 Transform3D effects, and a nicely studied HTML to give you the effect of the screen scrolling up (actually, only the images are moving - and not scrolling - while the screen is always in the same Y position).
The same effect is used to create the percetion of depth, by moving the houses in background slower than the ones in front.
This effect is called PARALLAX SCROLLING .
A good javascript library you could start looking at for Parallax effects is Stellar.js
You can take a look at some great sites made with Stellar.js, especially Nike and Saucony.
Hope this answer saved you some time,
good luck on your studies ;)

this is what you want: Jquery Parallax Scrolling effect - Multi directional
open the fiddle from the bounty-awarded answer and keep the right arrow key down.
I've made a horizontal menu.
What it should be doing is having the elements under it line up along the right side in an orderly fashion. Instead, it jumps throughout page seemingly randomly, and has other issues such as flickering. I've been stuck on making it for awhile and would love some tips to resolve these issues. Here is a JS FIDDLE showing the issue, all stripped down.
Thanks.
Here are current issues:
The submenu does not align perfectly with the right side of main nav even though its offset is calculated by main navs offset + width.
Flickering(Moderately solved using large borders)
Elements sometimes doesn't catch mouseover, to reproduce I am moving my mouse all the way down and off and up it and off
The menu slide out part goes to the bottom right of the page, in a somewhat random order, and continues to move further away (yikes)
The solution to the flickering issue is to make the submenu items overlap or touch. This can be done by adding a one-pixel white border to the menu item.
When it comes to the alignment issue (which could have been intended), you need to add (twice) the element's padding and border as the width is inside the padding.
