Fullpage js navigation dots don’t change in size as I scroll between sections. Other navigation interactions work fine: the dots increase in size on hover and they are linked/anchored to the appropriate sections.
How can I make the dots change in size upon section transition? Thank you!
The default navigation bullets change size as you can see here. So unless you provide us with an codepen or jsfiiddle where we can't see this, my best guess is that you are not importing the CSS file or you are overwriting it's styles somehow.
The new Unity 4.6 comes with a new GUI, when I change de resolution on Unity the UI Button scales perfectly but when I test on the Nexus 7 device the Button looks too small. Any idea how to solve this?
Unity's new GUI system uses "anchors" to control how gui elements (like buttons) scale in relation to their parent container.
Unity has a tutorial video on how to use the new "Rect Transform" component (where the anchors are configured) here: http://unity3d.com/learn/tutorials/modules/beginner/ui/rect-transform.
The last half of the tutorial is all about anchors. That page has links to the entire tutorial series. It's not too long. You should watch the whole thing.
Specific to your question:
The anchors are visible in your first screen shot. They are those 4 little arrows at the top left of your button.
Right now, your button is only anchored by it's top left corner.
The two right anchors need to be dragged to the right so that the right edge of your button is anchored to a space inside its parent container.
Depending on your situation, the two bottom arrows may need to be dragged down so that the bottom edge of your button is anchored as well.
The video I linked above covers all this in detail.
Lastly, for the font size to scale nicely on different resolutions, you will need to add and configure a reference resolution component to the base canvas of your UI, as Ash-Bash32 wrote earlier.
Update: The best way to add a Reference Resolution component is through the inspector window for the base canvas in your UI.
1) click the "Add Component Button" at the bottom of the inspector.
2) type the word "Reference" in the search filter field.
3) select the "Reference Resolution" component in the search results.
The Reference Resolution is now renamed as Canvas Scaler.. Along with the renaming they have added many more features for the dynamicity of the Canvas. You can go through the Unity Doc of Canvas Scaler and also take a look at this article for a practical example of how and why to use Canvas Scaler. Also make sure you use the Anchor Points to good effect to make this more robust...
To Scale UI added the ReferenceResolution Component to the Canvas you want to scale.
P.S. Theres no Documention for ReferenceResolution
If you want the button to be the same size for all screens and resolutions, you have to add the canvas scaler component to the canvas and the set the screen match mode to: match width or height, here is the link to the docs, this helps a lot if you want to aim to different sizes or resolutions:
http://docs.unity3d.com/Manual/HOWTO-UIMultiResolution.html
This becomes giant and convoluted once you start laying things out in code AND using a canvas scaler, so I wish to provide a thorough answer to save someone the hours I went through.
First, don't use anchoredPosition to position anything, unless you fully realize it is a 0.0 to 1.0 number. Use the RectTransform localPosition to do the actual laying out, and remember it's in relation to the parent anchor. (I had to lay out a grid from the center)
Second, put a canvas scaler on the parent layout object AND the inner ui pieces. One makes the layout in the right position, the other will resize your elements so they actually show up right. You can't rely on the the parent unless the children also have scalers (and Graphic Raycasters to touch them).
Third, if you have a scaler, DON'T use Screen.width and height, instead assume the screen is the same value you put for the scalers (hopefully you used the same, or know what you're doing). The screen width always returns the actual device pixels, retina devices too, but the canvas scalers DO NOT account for this. This probably gives unity the one remaining way to find actual screen dpi if your game wants it. Edit: This paragraph applies to any parent canvas connected to the code doing your laying out. Not stray canvases, you can probably mix it up. Just remember unity's guidelines on performance with canvases.
Fourth, the canvas is still a bit buggy. Even with the above working, some things don't render until you delete and recreate a canvas, if you re-open the scene or it crashes. Otherwise, the above is the general "rules" I've found.
To center a "grid of things" you can't just use half of the canvas scaler's width or height, you have to calculate the height of your grid and set the offset by half of it, otherwise it will always be slightly off. I just added this as an extra tip. This calculation works for all orientations.
So as far as I'm concerned, overflow:hidden does hide the scrollbar, but makes it impossible to scroll (at least scrolling doesn't work in Firefox).
I have a scroller-slider on my homepage - it scrolls automaticaly to lower full-screen elements one by one and then comes back to the first element and starts over. It looks really nice in my opinion, but the scrollbar is visible - I would like to make it invisible. With overflow: hidden the scrolling mechanism doesn't work.
Any idea how to do it?
You can hide scrollbar with CSS - wrap your scrollable container into another one with overflow:hidden and less height/width (depending on scroll you want to hide - vertical or horizontal one). This way helps if you have static container/content sizes. If container can be resized or size depends on content - you will have to use JS solution to calculate container size.
I am looking to make a "10 foot" useable site for TV. Ideally it would have a full screen background image a small header where the nav will be placed and under it a container for the content. I would like for the container itself to have a scroll bar, as oppose to the browser having the scroll bar, since this would lose my top header.
Basically top header should be fixed, an image for a background, and a container that scrolls inside itself. I have tried finding templates or a starting point online for this with very poor results. The best i have found so far is http://css-tricks.com/examples/FullPageBackgroundImage/progressive.php
This is almost what I need except the container overflows the screen so the scroll bar is in the browser. Also this article was written in 2010, maybe there is a better way to achieve this now?
You can use CSS to style the div.
div.scroll {
background-color:#00FFFF;
width:100px;
height:100px;
overflow-y:scroll;
}
Then... all you have to do is position that div as you want.
We have a simple modal in our web application.
It's nothing special and is built on twitters bootstrap library.
It contains a backdrop that is a semi transparent white background with position: fixed and width and height set to 100%.
The modal itself, however, is not statically positioned but absolutely positioned, this is because the modal might be taller than the viewport and we don't want scrolling in the modal.
Here's the dilemma, when the backdrop is present the scrolling is far from smooth in Google Chrome, if I change the position of the backdrop to absolute everything is fine.
This has the obvious downside of not covering the entire page.
I tried to reproduce it with a JSFiddle but I couldn't (most likely due to the fact that we a lot more content on our site).
Nonetheless here is my attempt: http://jsfiddle.net/LdC4w/
So, any ideas?
Oh, and I can add that having a background image instead of opacity is not an option.
