I have a few radio buttons that I'm styling with PNG background images, using :hover to swap out the background image for one with a surrounding halo. The halo areas from adjacent radio buttons overlap, so they should not be part of the clickable area. Yet they are still part of the same image.
Ideally, I'd like to show the halo behind the padding area, so I need the content area of each radio button to be clickable, but not the padding. I can't find any CSS attribute that controls this. The pointer-events attribute is almost, but not quite what I need, and most of its values apply only to SVG anyway.
All that Google searches turn up are pointers on how to use the padding to make the clickable area bigger, not smaller. I can use CSS3-only attributes if necessary, but would prefer not to add any extra markup to my HTML.
Any bright ideas?
I'm afraid this is not possible without adding extra markup. If you were using divs you could add a pseudo-element that contains the background image, but unfortunately it is not possible on input elements (:before and :after).
You need to add a wrapper div that handles the background image:

Also, beware of the usability issues this may cause, a hover effect usually implies that the element is clickable, so in the jsfiddle I added a cursor: pointer so it is clear the precise area where you are supposed to click.
If you attach an image with the halo effect you want to achieve it may be possible to achieve the effect in css3, removing the need for extra markup.
You should change it to margin. Than should be not clickable.
if your border or padding is thicker, then You can keep a new div on it with the position absolute,higher z-index and the alignments using 'top' and 'left'

In Bootstrap carousels there is apparently an invisible box that surrounds the indicator circles. I gave it a red border so I could play with it. All of my attempts to resize it or give it a different z-index only add to the problem.. I want to get rid of it because it blocks the items on the slide from being clickable. Does anyone know what its purpose is and how to disable it? I would like to keep the indicators themselves, but not the oversized invisible thing. Thanks in advance!

You can use pointer-events:none for the div, and then the items under it will be clickable. If you need the indicators to be clickable, you can use pointer-events:all; on them.

strong textSeems like a common problem, but in my case it's complicated by a few extra requirements, so what I found on SO and MDN didn't lead me to a full solution.
Simple premise:
Horizontal nav bar, full width of the page, semi-transparent background, variable number of tabs (extra space filled with same background as tabs).
Easy, right? Give the container element rgba background, set nav items display:inline or float them left and you're golden.
Complication 1: Active tab has to have a triangular cutout (see pic).
Ok, I can have a cutout by setting background-image to a png with transparent bit. The background of the parent element would get in the way - so set background to individual elements instead of parent.
What about the variable width "empty space" past the tabs (see pic)? Ok, put an empty element with a larger than life width, and cut it off with overflow:hidden on the parent.
Complication 2:
Buttons need tooltips on hover.
Ah, the thrill! The suspense! overflow:hidden won't do unless I put tooltips outside of nav div altogether (which would probably work - but seems smelly).
So, here are a few things I tried:
Old implementation which doesn't have the "filler" element width problem but clips off half a tooltip (with overflow:hidden):
http://codepen.io/istro/pen/aHcdi
Messing with display:table seems to give little control over how display:table-cell div width is decided, also needs content to display the div in the first place. Content can be moved away, but still no good (didn't even add a tooltip here):
http://codepen.io/istro/pen/uIcfn
Messing with floats (tooltip sorta where I'd want it to be more or less), but clueless how to make the last "filler" element fit remaining width:
http://codepen.io/istro/pen/aIGxB
So the question - how could I make a div to fill the remaining width with CSS only? Or perhaps I'm asking the wrong question altogether, in which case what ideas would I use to implement it cleanly?
Thanks!!!
i'm having a rather unique problem with CSS and DIV with/without borders.
Now, when i use the DIV without any borders, there is a kind of automatic padding! when i add a border, the padding disappears.
Even when i use "margin:0;padding:0" it still doesn't clear off the padding.
does anyone have any ideas why it's behaving like this? As a result, i had to use a border with the same color as the page background, but now i have same problem with a set of 3 DIV that should be right next to each other and CANNOT have any borders at all.
HELP!
I need to create this layout and I'd like to do as much of it as possible with CSS, rather than using images and whatever.
As such, how can I do this in CSS? (if at all?)
As you can see, there is the image behind, with the button overlaid with padding. The bit that I'm struggling with is creating the curves on the IMAGE above and to the left of the button and bottom to the right of the button (I've pointed them out on the pic below).
Any help would be great.
Thanks
I know just enough CSS to be dangerous so I can't detail every step, but I think you can approach it like this:
Split the background image into two separate images both at a z-index of 0 at the height of the top of the grey box. I think you can use two div's that reference the same original image with different offsets (similar to CSS Sprites) but I don't know the details of how to do that. The left edge of the lower div would start where the grey box ends. Round the lower-left corner of each "image" div.
Add the grey box at a z-index of 1 with appropriate rounding, and then the blue box at a z-index of 2, again with appropriate rounding.
The background of the block element containing all of this would also have to be grey to match the grey border and properly fill in grey where your right-most arrow is pointing.
You don't have to split your image at all, only the container divs.
Let me detail a bit:
You can have your image set as a background image instead of putting it in a src attribute of an img tag. This technique is most commonly used when working with CSS sprites.
So, if you have you uppermost div at a constant width and height, if you try to apply the background image in it, you'll see it fits very nice.
On the bottom, you have two divs or whatever block element you'll like, just be sure to put fixed width and height, so the background will be applied and you will be able to actually see it.
Then all you have to do is fiddle with css background-position to adjust the SE chunk of image.
I'll be putting a small demo together to better illustrate the idea.
After you have a big div at the top, and two smaller at the bottom, where two of them share the same background-image, but with different background-position, you can safely add some css3 border-radius to fit your roundness needs. You can also use some tool like http://css3generator.com/ to add a compatibility layer on all browsers with ease.
That is very easy to realize with pure css. The page you have shown is divided into 3 divs without any margin. You only need to set the right border radius for each div.
This is a function of the background image, which is a css element if that's what you mean, but it is not a seperate attribute for a selector, at least not in standard CSS. Wait until CSS3 becomes more prevelant, then it's corner-radius or some such thing.
Well it's 3 probably 3 seperate divs, a hole "burned" into the background image, or a div being overlayed for the button.
The best way to figure out how it's done is to read the source of the page you found it on.
For convenience:
If you have a webkit based browser like chrome or safari then enable developper mode mouse over the button "right click" and choose inspect element. Otherwise you can pour over the page source until you find what you want.
I need to modify a website to make the clickable zone of all links bigger for mobile devices. I gave all links a transparent border and a negative margin of the same size, to not affect the text-flow. Now this works like a charm. But not on elements that have a background. The background spreads out to the transparent border. This is behaviour seams to be consistent among all browsers.
http://jsfiddle.net/hq65C/1/ here a other example: http://jsfiddle.net/DytDA/
Why is this? I was always thinking that the border is outside of the element. How could I fix this. (I need a solution that does not require to modify the HTML).
How about background-clip: padding-box;?
Demo
i think that if the border were outside the element, the behaviour you are behind (that clicking on the border behaves as clicking inside the element) wouldn't work either
if the background-image is not repeated, you can set background-position x position to the same amount that your border width. else, you can also try setting the border-color to the same as the color behind the element, but if it is an image, good luck
CSS background fills the area of the border, with the border-color layering over this.
As you have a transparent border, it is displaying the background-color behind it.
With plain HTML/CSS, I'm not sure there is a way around this.
This jsFiddle demostrates this:
http://jsfiddle.net/hq65C/8/
try this:
<span style="background: red">link</span> test test test <br/>
test test test
notice: the span means an inline element with another style (other CSS values). other that div which will force a new block.
