CSS - box-shadow tricks? - css

I have an element above a div that is styled to become oval-shaped.
I want to create a shadow on this div as well as the oval shaped element
but I want the shadow on the oval-shaped element to be below the div.
I'm using a box-shadow in the div as well as the oval.
I dunno if there is a code to crop a certain part on the shadow so that I can satisfy the request xD
The layer sequence would be div-shadow, oval-shadow, div, oval.
for reference, you can check the link below.

You could simply use :
position:relative;/* this is what it was meant for on the first place move at screen element */
top:15px;/*to tune with radius value */
EXAMPLE
alternative with visual bug is :
box-shadow : 0px 15px white,/*to tune with radius value */
0px 25px RGB(5, 80, 150);/*add tuning to width expected */

Firefox not rendering correctly with: border-radius,box-shadow and border

In the example bellow:
http://jsfiddle.net/Du8f6/3/
Im setting inner shadow to the container and 10px border with border-radius set to 50%.
And the result is weired thin white border outside the container border.
The thin white border is visible in:
mozilla firefox
ie 11
and its not visible in:
opera
safari
chrome
any suggestions for fixing this are welcome.
It's because the way the border is rendered: painted over the div. It's another "half pixel" issue and the border color mixs with the div background color... Take a look to Border-radius: 50% not producing perfect circles in Chrome or IE11 draws small line between positioned elements . Those are not the same issue, but have the same origin.
Probably your easier workaround is to skip out the border width of the div and set up a "fake" border using the background of a new wrapper div:
In your html:
<div class="fakeborder"><div class="sub">Hm</div></div>
and in your css:
.sub {
...
border: 0px solid black;
...
}
.fakeborder{
margin:0;
padding:10px; /*The fake border width*/
background:black; /*The fake border color*/
}
I had a similar issue.
Even if I set
box-shadow:0 0 0 rgba(0,0,0,0);
to the element just because I didn't want a box-shadow for that element and I thought I could override the property like this.
That was working in webkit browsers, but FF was still rendering a thin shadow.
A better solution and the best practice to override a css property to its default, it is obviously set it to its default (dumb!)
box-shadow: none

Border-radius rendering bug when in overflow: hidden

I have a bug in the rendering of border-radius under all major browsers (tested: IE 9, Chrome, Firefox).
What happen is that I have a menu bar with border-radius, and in there some links width a background color. In order to keep the button inside the shape of the menu, I set a overflow hidden on the menu container. Until there all goes well, but then, there's a little white line appearing on the corner edge.
I made a reduced test case here: http://dabblet.com/gist/3828561
Anyone have a solution to overcome this one? Thanks!
A dimensions-dependent solution...but maybe that's OK since it's a menu bar not a content holder? Anyway, you can set border-radius on your inner elements, give the parent a height, and also use that height value for the line-height of the inner elements.
Once you apply the height/line-height, you don't have to use overflow: hidden.
Since your menu bar has a border radius of 3px, apply the same rounding to the appropriate corners of the first menu item like so:
.outer .inner:first-of-type { border-radius: 3px 0 0 3px; }
And make the corresponding corners of the bar even more rounded, to hide them beneath the first menu item:
.outer { border-radius: 10px 3px 3px 10px; }

Positioning background image, adding padding [duplicate]

This question already has answers here:
CSS: Background image and padding
(9 answers)
Closed 3 years ago.
I'd like to add a background to a div, position right center, but!, have some padding to the image. The div has padding for the text, so I want to indent the background a little. probably makes most sense w/ example:

Thanks!
Updated Answer:
It's been commented multiple times that this is not the correct answer to this question, and I agree. Back when this answer was written, IE 9 was still new (about 8 months old) and many developers including myself needed a solution for <= IE 9. IE 9 is when IE started supporting background-origin. However, it's been over six and a half years, so here's the updated solution which I highly recommend over using an actual border. In case < IE 9 support is needed. My original answer can be found below the demo snippet. It uses an opaque border to simulate padding for background images.
#hello {
padding-right: 10px;
background-color:green;
background: url("https://placehold.it/15/5C5/FFF") no-repeat scroll right center #e8e8e8;
background-origin: content-box;
}
<p id="hello">I want the background icon to have padding to it too!I want the background icon twant the background icon to have padding to it too!I want the background icon to have padding to it too!I want the background icon to have padding to it too!</p>
Original Answer:
you can fake it with a 10px border of the same color as the background:
http://jsbin.com/eparad/edit#javascript,html,live
#hello {
border: 10px solid #e8e8e8;
background-color: green;
background: url("http://www.costascuisine.com/images/buttons/collapseIcon.gif")
no-repeat scroll right center #e8e8e8;
}
this is actually pretty easily done. You're almost there, doing what you've done with background-position: right center;. What is actually needed in this case is something very much like that. Let's convert these to percentages. We know that center=50%, so that's easy enough. Now, in order to get the padding you wanted, you need to position the background like so: background-position: 99% 50%.
The second, and more effective way of going about this, is to use the same background-position idea, and just use background-position: 400px (width of parent) 50%;. Of course, this method requires a static width, but will give you the same thing every time.
Method 1 (99% 50%)
Method 2 (400px 50%)
There is actually a native solution to this, using the four-values to background-position
.CssClass {background-position: right 10px top 20px;}
This means 10px from right and 20px from top.
you can also use three values the fourth value will be count as 0.
you can use background-origin:padding-box; and then add some padding where you want, for example: #logo {background-image: url(your/image.jpg); background-origin:padding-box; padding-left: 15%;}
This way you attach the image to the div padding box that contains it so you can position it wherever you want.
In case anyone else needs to add padding to something with background-image and background-size: contain or cover, I used the following which is a nice way of doing it. You can replace the border-width with 10% or 2vw or whatever you like.
.bg-image {
background: url("/image/logo.png") no-repeat center #ffffff / contain;
border: inset 10px transparent;
box-sizing: border-box;
}
This means you don't have to define a width.
first off, to be a bit of a henpeck, its best NOT to use just the <background> tag. rather, use the proper, more specific, <background-image> tag.
the only way that i'm aware of to do such a thing is to build the padding into the image by extending the matte. since the empty pixels aren't stripped, you have your padding right there. so if you need a 10px border, create 10px of empty pixels all around your image. this is mui simple in Photoshop, Fireworks, GIMP, &c.
i'd also recommend trying out the PNG8 format instead of the dying GIF... much better.
there may be an alternate solution to your problem if we knew a bit more of how you're using it. :) it LOOKS like you're trying to add an accordion button. this would be best placed in the HTML because then you can target it with JavaScript/PHP; something you cannot do if it's in the background (at least not simply). in such a case, you can style the heck out of the image you currently have in CSS by using the following:
#hello img { padding: 10px; }
WR!
To add space before background image, one could define the 'width' of element which is using 'background-image' object. And then to define a pixel value in 'background-position' property to create space from left side.
For example, I'd a scenario where I got a navigation menu which had a bullet before link item and the bullet graphic were changeable if corrosponding link turns into an active state. Further, the active link also had a background-color to show, and this background-color had approximate 15px padding both on left and right side of link item (so on left, it includes bullet icon of link too).
While padding-right fulfill the purpose to have background-color stretched upto 15px more on right of link text. The padding-left only added to space between link text and bullet.
So I took the width of background-color object from PSD design (for ex. 82px) and added that to li element (in a class created to show active state) and then I set background-position value to 20px. Which resulted in bullet icon shifted inside from the left edge. And its provided me desired output of having left padding before bullet icon used as background image.
Please note, you may need to adjust your padding / margin values accordingly, which may used either for space between link items or for spacing between bullet icon and link text.

CSS3 border radius + different border width, ugly transition

I got another tricky CSS3 situation that I'm breaking my head on. I'm styleing a form with CSS to have a 10px border on the sides and a 12px border on the bottom, in combination with a 15px border radius.
Unfortunately, the point where the 12px and the 10px borders meet the transition is not gradual but there's a 2px chunk sticking out of the inside of the border. Example (sizes magnified for clarity):
http://jsfiddle.net/LnKND/1/
Any idea how to fix this using only css and no extra elements? Or is this just the way it's rendered currently and should I find another solution?
Add
border-bottom-left-radius:10px 20px;
border-bottom-right-radius:10px 20px;
reference : http://www.w3.org/TR/css3-background/#the-border-radius
for mozilla use
-moz-border-radius-bottomright
-moz-border-radius-bottomleft
if you want, although it handles the issue automatically (if you fix the typo p to px in the example).

Hide Section of a Box Shadow

Disclaimer: I have already seen the following questions and their solutions did not apply to me even though they are very similar situations:
Creating a CSS3 box-shadow on all sides but one
How to add drop shadow to the current element in a tab menu?
CSS shadows on 3 sides
Simply put, I am trying to add a -moz-box-shadow of 0 0 10px to the .current_page_item class that is applied to the currently active tab in the tab navigation at the top of my website. The website does not yet include the actual box-shadow or any of these changes, I have only been playing with these modifications in firebug for now before I actually publish them. Naturally this causes the shadow to appear on all sides, and so the bottom edge's shadow overlaps into the .content div which stores all of the blog's actual content, i.e. posts.
Based on what I have seen so far, it seems like I should set the z-index of something, not sure what (I have tried ul.menu) to something lower and the z-index of the .content div to something higher, but this seems to have no effect.
I am just wondering if this is normal behavior and if not, if someone could help me out with this situation.
Thanks, I really appreciate it.
EDIT: I put box-shadow in the post earlier, but I meant the respective specific directives, such as -moz-box-shadow. That was not the problem I was having.
You will need to add overflow:hidden on the ul.menu as honeybuzzer mentions, but since that would also cut-off the top shadow you should add some padding-top to the ul.menu as well..
overflow:hidden on ul.menu seems to get rid of the bottom shadow.
clip-path is now (2020) an excellent solution for hiding specific box-shadow edges if you're wanting the box-shadow to be cut off "clean" like this:
.shadow-element {
width: 100px;
height: 100px;
border: 1px solid #333;
box-shadow: 0 0 15px rgba(0,0,0,0.75);
clip-path: inset(0px -15px 0px 0px);
}
<div class="shadow-element"></div>
Simply apply the following CSS to the element in question:
box-shadow: 0 0 Xpx [hex/rgba]; /* note 0 offset values */
clip-path: inset(Apx Bpx Cpx Dpx);
Where:
Apx sets the shadow visibility for the top edge
Bpx right
Cpx bottom
Dpx left
Enter a value of 0 for any edges where the shadow should be hidden and a negative value (the same as the box-shadow blur radius - Xpx) to any edges where the shadow should be displayed.
This solution removes the need to apply styling to a parent element, which gives more flexibility.
