How to create a drop shadow only on one side of an element

Question

Is there a way to drop the shadow only on the bottom   I have a menu with 2 images next to each other  I don t want a right shadow because it overlaps the right image  I don t like to use images for this so is there a way to drop it only on the bottom like    box-shadow-bottom  10px  FFF  or similar   -moz-box-shadow  0px 3px 3px  000  -webkit-box-shadow  0px 3px 3px  000  box-shadow-bottom  5px  000     For IE 8    -ms-filter   progid DXImageTransform Microsoft Shadow Strength 4  Direction 180  Color   000000        For IE 5 5 - 7    filter  progid DXImageTransform Microsoft Shadow Strength 4  Direction 180  Color   000000

It is better to look up shadow     header      -webkit-box-shadow  0 -8px 73px 0 rgba 0 0 0 0 2       -moz-box-shadow  0 -8px 73px 0 rgba 0 0 0 0 2       box-shadow  0 -8px 73px 0 rgba 0 0 0 0 2       this code is currently using on stackoverflow web

I also needed a shadow but only under an image and set in slightly left and right  This worked for me    box-shadow      -webkit-box-shadow  5px 35px 30px -25px  888888        -moz-box-shadow  5px 35px 30px -25px  888888             box-shadow  5px 35px 30px -25px  888888      The element this is applied to is a page-wide image  980px x 300px    If it helps when fiddling with the settings  they run as follows   horizontal shadow  vertical shadow  blur distance  spread  i e  shadow size   and color

It s always better to read the specs  There is no box-shadow-bottom property  and as Lea points out you should always place the un-prefixed property at the bottom  after the prefixed ones   So it s    x000D   x000D   shadow   x000D    -webkit-box-shadow  0px 2px 4px  000000  x000D    -moz-box-shadow  0px 2px 4px  000000  x000D    box-shadow  0px 2px 4px  000000  x000D    x000D   lt div class  shadow  gt Some content lt  div gt  x000D   x000D   x000D

If your background is solid  or you can reproduce it using CSS   you can use linear gradient that way    x000D   x000D  div   x000D    background-image  linear-gradient to top  rgba 0  0  0  0  0   rgba 0  0  0  0 3  5px   fff 5px   fff 100   x000D    x000D   lt div gt  x000D   lt p gt Foobar lt  p gt  x000D   lt p gt test lt  p gt  x000D   lt  div gt  x000D   x000D   x000D    This will generate a 5px gradient at the bottom of the element  from black at 30  opacity to completely transparent  The rest of the element has white background  Of course  changing the last 2 color stops of the linear gradient  you could make the background completely transparent

You could also use clip-path to clip  hide  all overflowing edges but the one you want to show   shadow     box-shadow  0 4px 4px black    clip-path  polygon 0 0  100  0  100  200   0 200       See clip-path  MDN   The arguments to polygon are the top-left point  the top-right point  the bottom-right point  and the bottom-left point  By setting the bottom edge to 200   or whatever number bigger than 100   you constrain your overflow to only the bottom edge  Examples    x000D   x000D   shadow     box-shadow  0 0 8px 5px rgba 200  0  0  0 5      shadow-top     clip-path  polygon 0  -20   100  -20   100  100   0  100       shadow-right     clip-path  polygon 0  0   120  0   120  100   0  100       shadow-bottom     clip-path  polygon 0  0   100  0   100  120   0  120       shadow-left     clip-path  polygon -20  0   100  0   100  100   -20  100        shadow-bottom-right     clip-path  polygon 0  0   120  0   120  120   0  120          layout for example     box     display  inline-block    vertical-align  top    background   338484    color   fff    width  4em    height  2em    margin  1em    padding  1em    x000D   lt div class  box  gt none lt  div gt   lt div class  box shadow shadow-all  gt all lt  div gt   lt div class  box shadow shadow-top  gt top lt  div gt   lt div class  box shadow shadow-right  gt right lt  div gt   lt div class  box shadow shadow-bottom  gt bottom lt  div gt   lt div class  box shadow shadow-left  gt left lt  div gt   lt div class  box shadow shadow-bottom-right  gt bottom right lt  div gt  x000D   x000D   x000D

Just use the spread parameter to make the shadow smaller    x000D   x000D   shadow   x000D    -webkit-box-shadow  0 6px 4px -4px black  x000D    -moz-box-shadow  0 6px 4px -4px black  x000D    box-shadow  0 6px 4px -4px black  x000D    x000D   lt div class  shadow  gt Some content lt  div gt  x000D   x000D   x000D    Live demo  http   dabblet com gist a8f8ba527f5cff607327  To not see any shadow on the sides  the  absolute value of the  spread radius  4th parameter  needs to be the same as the blur radius  3rd parameter

You can do that like this   General syntax   selector      box-shadow  topBoxShadow  bottomBoxShadow  rightBoxShadow  leftBoxShadow     Example  we want to make only a bottom box shadow with red color    so to do that we have to set all the sides options where we have to set the bottom box shadow options and set all the others as empty as follow    box        -moz-box-shadow  0 0 0 transparent  0 0 10px red  0 0 0 transparent  0 0 0 transparent      -o-box-shadow  0 0 0 transparent  0 0 10px red  0 0 0 transparent  0 0 0 transparent      -webkit-box-shadow  0 0 0 transparent  0 0 10px red  0 0 0 transparent  0 0 0 transparent      box-shadow  0 0 0 transparent  0 0 10px red  0 0 0 transparent  0 0 0 transparent

UPDATE 4  Same like update 3 but with modern css   less rules  so that no special positioning on the pseudo element is required    x000D   x000D   box   x000D      background-color   3D6AA2  x000D      width  160px  x000D      height  90px  x000D      position  absolute  x000D      top  calc 10  - 10px   x000D      left  calc 50  - 80px   x000D    x000D   x000D   box-shadow after   x000D      content     x000D      position absolute  x000D      width 100   x000D      bottom 1px  x000D      z-index -1  x000D      transform scale  9   x000D      box-shadow  0px 0px 8px 2px  000000  x000D    x000D   lt div id  box  class  box-shadow  gt  lt  div gt  x000D   x000D   x000D    UPDATE 3  All my previous answers have been using extra markup to get create this effect  which is not necessarily needed  I think this a much cleaner solution    the only trick is playing around with the values to get the right positioning of the shadow as well as the right strength opacity of the shadow  Here s a new fiddle  using pseudo-elements   http   jsfiddle net UnsungHero97 ARRRZ 2   HTML   lt div id  box  class  box-shadow  gt  lt  div gt    CSS   box       background-color   3D6AA2      width  160px      height  90px      margin-top  -45px      margin-left  -80px      position  absolute      top  50       left  50       box-shadow after       content          width  150px      height  1px      margin-top  88px      margin-left  -75px      display  block      position  absolute      left  50       z-index  -1      -webkit-box-shadow  0px 0px 8px 2px  000000         -moz-box-shadow  0px 0px 8px 2px  000000              box-shadow  0px 0px 8px 2px  000000      UPDATE 2  Apparently  you can do this with just an extra parameter to the box-shadow CSS as everyone else just pointed out  Here s the demo   http   jsfiddle net K88H9 821   CSS  -webkit-box-shadow  0 4px 4px -2px  000000     -moz-box-shadow  0 4px 4px -2px  000000            box-shadow  0 4px 4px -2px  000000    This would be a better solution  The extra parameter that is added is described as      The fourth length is a spread   distance  Positive values cause the   shadow shape to expand in all   directions by the specified radius    Negative values cause the shadow shape   to contract    UPDATE  Check out the demo at jsFiddle  http   jsfiddle net K88H9 4   What I did was create a  shadow element  that would hide behind the actual element that you would want to have a shadow  I made the width of the  shadow element  to be exactly less wide than the actual element by 2 times the shadow you specify  then I aligned it properly   HTML   lt div id  wrapper  gt       lt div id  element  gt  lt  div gt       lt div id  shadow  gt  lt  div gt   lt  div gt    CSS   wrapper       width  84px      position  relative     element       background-color   3D668F      height  54px      width  100       position  relative      z-index  10     shadow       background-color   3D668F      height  8px      width  80px      margin-left  -40px      position  absolute      bottom  0px      left  50       z-index  5      -webkit-box-shadow  0px 2px 4px  000000         -moz-box-shadow  0px 2px 4px  000000              box-shadow  0px 2px 4px  000000      Original Answer  Yes  you can do this with the same syntax you have provided  The first value controls the horizontal positioning and the second value controls the vertical positioning  So just set the first value to 0px and the second to whatever offset you d like as follows   -webkit-box-shadow  0px 5px  000000     -moz-box-shadow  0px 5px  000000          box-shadow  0px 5px  000000    For more info on box shadows  check out these     http   www css3 info preview box-shadow  https   developer mozilla org en css -moz-box-shadow Browser compatibility http   www w3 org TR css3-background  the-box-shadow   I hope this helps

If you have a fixed color on the background  you can hide the side-shadow effect with two masking shadows having the same color of the background and blur   0  example   box-shadow       -6px 0 white            Left masking shadow       6px 0 white             Right masking shadow       0 7px 4px -3px black    The real  slim  shadow     Note that the black shadow must be the last  and has a negative spread  -3px  in order to prevent it from extendig beyond the corners   Here the fiddle  change the color of the masking shadows to see how it really works     x000D   x000D  div  x000D      width  100px  x000D      height  100px  x000D      border  1px solid pink  x000D      box-shadow  -6px 0 white  6px 0 white  0 7px 5px -2px black  x000D    x000D   lt div gt  lt  div gt  x000D   x000D   x000D

Another idea based on the answer of  theengineear where I will use inset instead of polygon  It s easier since it works the same way as margin or padding  I will also rely on CSS variable to easily define all the different cases   x000D   x000D   shadow     box-shadow  0 0 8px 5px rgba 200  0  0  0 5     clip-path inset var --t 0  var --r 0  var --b 0  var --l 0       top   --t -100      right   --r -100     bottom   --b -100      left   --l -100         layout for example      box     display  inline-block    vertical-align  top    background   338484    color   fff    width  4em    height  2em    margin  1em    padding  1em    x000D   lt div class  box  gt none lt  div gt   lt div class  box shadow top right left bottom  gt all lt  div gt   lt div class  box shadow top  gt top lt  div gt   lt div class  box shadow right  gt right lt  div gt   lt div class  box shadow bottom  gt bottom lt  div gt   lt div class  box shadow left  gt left lt  div gt   lt div class  box shadow bottom right  gt bottom right lt  div gt   lt div class  box shadow bottom top  gt top bottom lt  div gt   lt div class  box shadow left top right  gt top left right lt  div gt   lt div class  box shadow left right  gt  left right lt  div gt  x000D   x000D   x000D

You could also just do a gradient on the bottom - this was helpful for me because the shadow I wanted was on an element that was already semi-transparent  so I didn t have to worry about any clipping    amp  after         content           width 100         height  8px        position  absolute        bottom  -8px        left  0        background  linear-gradient to bottom  rgba 0 0 0 0 65  0  rgba 0 0 0 0  100            Just make the  bottom  and  height  properties match and set your rgba values to whatever you want them to be at the top   bottom of the shadow

How about just using a containing div which has overflow set to hidden and some padding at the bottom  This seems like much the simplest solution   Sorry to say I didn t think of this myself but saw it somewhere else      Using an element to wrap the element getting the box-shadow and a overflow  hidden on the wrapper you could make the extra box-shadow disappear and still have a usable border    This also fixes the problem where the element is smaller as it seems  because of the spread       Like this    wrapper   padding-bottom  10px  overflow  hidden     elem   box-shadow  0 0 10px black          Content goes here      Still a clever solution when it has to be done in pure CSS    As said by Jorgen Evens
