fullPage.js - can't view content higher than section - html

I have page based on fullPage.js and Bootsrap. By default is content in section vertically centered. But my content is dynamic and changes on click. It means, that my content has on every click different height and it cause div jumping on page.
Disabling vertical center solve the problem, but only for desktop. On smaller screen (mobiles, tablets) I can't see whole content in section.
With vertical center enabled the section is high as content.
Live example is more than word so:
Example with verticalCenter enabled (not working)
Example with verticalCenter disabled (not working)

Finally the solution was specify container height.

I would encourage you to use the responsiveWidth or responsiveHeight options provided in fullpage.js. That's going to create the best user experience for small screen devices.
But if you still want autoScrolling then you can always go for the scrollOverflow option as in this example and to adjust the scroll bar dynamically you would have to call $.fn.fullpage.reBuild() on any click that changes triggers a change in the section's height.

Flexbox elements overlap on window resize

I am building a landing page with 3 sections (haven't coded the 3rd section yet).
Each section needs to be 100% of the screen.
Top 2 sections have 2 columns each.
I am using Flexbox for this, and everything looks great as long as the browser is in full screen, and the sections have no content. When I start adding content inside the sections, then resize the window, sections start overlapping, especially when resizing only vertically.
When resizing horizontally it's not a problem, since I can switch flex-direction:column; to flex-direction:row; to get them to stack.
How can I get a 100% view of the section while making everything responsive when window is resized and prevent overlap?
Would CSS Grid be a better option here?
Here's a Code Pen. Please slide the code pane up, then resize your window, and you'll notice how the second section overlaps on top of the first section's button, text, and image.

If you try removing the button, paragraph, and image from the html, then the problem is gone, and on resize the sections don't overlap...
Thanks!
You can use #media queries for different size screens. So you can display everything differently depending on the screen size. You can view the documentation here.
Maybe put overflow:hidden on section

Complicated layout with fixed and variable width, tabs using visibility and more

I have a rather complicated layout.
At the top and bottom are fixed header/footer.
The central display is broken up into two panels:
the left panel is hideable (may be visible, may not); if it is visible then it has a fixed width. It has a scroll within it if needed.
the right panel is always visible and has a variable width. It is scrolled by the window's scroll bar.
The right panel then consists of two parts that each fill the width of the panel - a set of tabs, of various heights (the visible tab should start at the top of the right panel, as the controlling buttons for those tabs are in the header), and directly below that a 'summary' box of unknown height, which comes immediately after the visible tab, no matter which tab we are looking at and how high it is.
Each of these panels/tabs/boxes consist of an outer div, and various internal divs as needed for the content.
The tabs are made by an outer div containing four inner divs, one after the other.
I can change the HTML and css as needed.
See https://jsfiddle.net/jvw8j62t/ (with thanks to JavaSpyder who provided the basic JSFiddle that I adapted for this demo)
I have tried various methods for the left and right panel, and the best one seems to be https://stackoverflow.com/a/4676510 but I would be happy to use a different method.
I then use jquery to hide/show the left panel (using display:none) and fix the right panel's left margin accordingly, though I am happy to use a different system for that.
However the tabs have to be made visible/invisible using visibility: visible and visibility: hidden (not display:none), because the contents of the tabs do not size correctly when using display:none. I cannot easily change this as there are three different libraries from three different sources having this issue.
This means that the different tabs' tops are then positioned incorrectly, because of the visibility css - they follow after each other, per https://stackoverflow.com/a/133064/1910690.
If I try different ways to make the top of the all the tabs fall at the top of the right panel then the summary box is positioned wrong and I can't align it to below the visible tab (changing position when you switch to a tab of a different height); or the right panel's scrolling is messed up; or the bottom of the tab disappears behind the footer; or one of several other problems.
Can anyone suggest a solution to the whole layout?
Is this the kind of thing you're looking for?
I used a flex container to create the left and right sections - the header and footer were easy enough with a fixed position. I used flex-shrink:0 on the left section so its width would be fixed, while leaving the right able to change to the screen width.
I'm not sure I did the tabs the way you specified, but feel free to correct if it isn't right. If you click on a tab, it will toggle visibility:hidden , but of course this leaves an empty gap. You said "the tabs have to be made visible/invisible using visibility: visible and visibility: hidden (not display:none), because the contents of the tabs do not size correctly when using display:none." Is this something we can also take a look at, or perhaps post in another question and link it here? If we could fix this problem, it could simplify this layout issue.
The left section is really another fixed position div with overflow:auto to give it the scrollbars. The height is handled by jquery.
Finally, clicking "Toggle Left Panel" will toggle the fixed position div and the width of the left section from 0 or 200.
With thanks to #JavaSpyder for his JSFiddle, and #Dhaval Chheda for the comment that inspired me...
I realised that I could use position:absolute on the tabs - NOT to position the visible tab correctly, but rather to REMOVE the invisible tabs from the layout of the page, leaving the visible tab and the summary ONLY in the layout of the page - and the result is as wanted.
See JavaSpyder's https://jsfiddle.net/JavaSpyder/fq43Lhez/ which also fixes an issue with the width of the right panel (my original solution is at https://jsfiddle.net/jvw8j62t/ ).
Again, thanks to JavaSpyder and Dhaval Chheda - could not have done it without you.

Create a frame for content without images/bg

I have a background that is a set of fairly complex gradients (done with CSS, not images). In the middle of the page is a fixed frame, and the content sits inside this frame. I can set overflow-y: auto on this frame to scroll the content, but I would like to be able to use the window to scroll instead.
Here is what the page looks like now:
I would like the scroll bar to be on the window instead. I can take the content outside of the frame and add margins as necessary, but the problem is that then the content will appear outside the frame. I could then cover it up on the top and bottom, but this is difficult/impossible because the background is not an image and is not solid.
Is there any way to have a transparent element at the top/bottom block text that scrolls under it? Can you somehow apply styles to content that overlaps?
Even the fanciest single-browser only solution that requires JavaScript is perfectly acceptable.
if all you're aiming at is hiding the scrollbar (and assuming you're ok with jQuery), i'd suggest to use something like slimScroll.
what's going on under the hood is simple: the designated container is assigned with overflow: hidden;, and attached with a hover handler - with the sole purpose of simulating a custom scrollbar in response to mouse-over events.
Try to explore jScrollPane features.
It's powerfull flexible JQuery plugin for working with scrollbars, possibly you will find solution with it.

How do I make a bottom fixed position menu in HTML?

I want to create a box-menu on the very bottom of the browser window.
It should stay at the bottom when the content doesn't fill up the entire screen
When the content overflows it should only be at the bottom when you scroll down (i.e. you can't see it if you don't scroll).
How do I do this?
I think what you are looking for is called a "sticky footer", and there are a couple of methods. I suggest you have a look at these sites:
http://ryanfait.com/sticky-footer/
http://www.cssstickyfooter.com/
Zoom in/out on each site in order to see how this appears when the content reaches the footer or does not.
Both methods fall short on one thing: They require you to know the height of the footer - but I have not seen any better solutions with only CSS.

overlay over scrollbar

I'm sorry if the title is not very good, any suggestions are welcome.
The entire page is an iframe onto another website (in this case, jquery.com just for demo purposes). I have an overlay "Hello World", and if you click on the X it minimizes it (click again it will open it).
My issue in this case is that it covers the scrollbar on the right.
I assume the reason is I have a CSS positioning the sidebar at right:0, however since it's an iFrame it doesn't count the scrollbar.
What are my options for working around that?
I thought of giving it some extra space, but how do I know if the page really has a scrollbar, or how big the scrollbar is?
Is there a way to place the overlay at a position WITHIN the iframe instead?
There is no way to detect the remote page's height or even if a scrollbar is present or not. Your only option, besides moving the sidebar to the left, is detecting the browser's scrollbar width and permanently shifting the overlay off the right edge this amount.
yes. just set the right to 40 for example right: 40px;
There is an example here that shows you how to detect if an iframe has a scrollbar:
How can I detect a Scrollbar presence ( using Javascript ) in HTML iFrame?
And there is also an example here that measures the scrollbar width

Once you know these you can place your overlay however many pixels from the right
