CSS overflow-x: visible; and overflow-y: hidden; causing scrollbar issue

Answer 1

I originally found a CSS way to bypass this when using the Cycle jQuery plugin. Cycle uses JavaScript to set my slide to overflow: hidden, so when setting my pictures to width: 100% the pictures would look vertically cut, and so I forced them to be visible with !important and to avoid showing the slide animation out of the box I set overflow: hidden to the container div of the slide. Hope it works for you.

UPDATE - New Solution:

Original problem -> http://jsfiddle.net/xMddf/1/ (Even if I use overflow-y: visible it becomes "auto" and actually "scroll".)

#content {
    height: 100px;
    width: 200px;
    overflow-x: hidden;
    overflow-y: visible;
}

The new solution -> http://jsfiddle.net/xMddf/2/ (I found a workaround using a wrapper div to apply overflow-x and overflow-y to different DOM elements as James Khoury advised on the problem of combining visible and hidden to a single DOM element.)

#wrapper {
    height: 100px;
    overflow-y: visible;
}
#content {
    width: 200px;
    overflow-x: hidden;
}

There is now a new way of addressing this issue - if you remove position: relative from the container which needs to have the overflow-y visible, you can have overflow-y visible and overflow-x hidden, and vice versa (have overflow-x visible and overflow-y hidden, just make sure the container with the visible property is not relatively positioned).

See this post from CSS Tricks for more details - it worked for me: https://css-tricks.com/popping-hidden-overflow/

Answer 3

another cheap hack, which seems to do the trick:

style="padding-bottom: 250px; margin-bottom: -250px;" on the element where the vertical overflow is getting cutoff, with 250 representing as many pixels as you need for your dropdown, etc.

I've run into this issue when trying to build a fixed positioned sidebar with both vertically scrollable content and nested absolute positioned children to be displayed outside sidebar boundaries.

My approach consisted of separately apply:

• an overflow: visible property to the sidebar element
• an overflow-y: auto property to sidebar inner wrapper

Please check the example below or an online codepen.

html {
  min-height: 100%;
}
body {
  min-height: 100%;
  background: linear-gradient(to bottom, white, DarkGray 80%);
  margin: 0;
  padding: 0;
}

.sidebar {
  position: fixed;
  top: 0;
  right: 0;
  height: 100%;
  width: 200px;
  overflow: visible;  /* Just apply overflow-x */
  background-color: DarkOrange;
}

.sidebarWrapper {
  padding: 10px;
  overflow-y: auto;   /* Just apply overflow-y */
  height: 100%;
  width: 100%;
}

.element {
  position: absolute;
  top: 0;
  right: 100%;
  background-color: CornflowerBlue;
  padding: 10px;
  width: 200px;
}

After some serious searching it seems i've found the answer to my question:

from: http://www.brunildo.org/test/Overflowxy2.html

In Gecko, Safari, Opera, ‘visible’ becomes ‘auto’ also when combined with ‘hidden’ (in other words: ‘visible’ becomes ‘auto’ when combined with anything else different from ‘visible’). Gecko 1.8, Safari 3, Opera 9.5 are pretty consistent among them.

also the W3C spec says:

The computed values of ‘overflow-x’ and ‘overflow-y’ are the same as their specified values, except that some combinations with ‘visible’ are not possible: if one is specified as ‘visible’ and the other is ‘scroll’ or ‘auto’, then ‘visible’ is set to ‘auto’. The computed value of ‘overflow’ is equal to the computed value of ‘overflow-x’ if ‘overflow-y’ is the same; otherwise it is the pair of computed values of ‘overflow-x’ and ‘overflow-y’.

Short Version:

If you are using visible for either overflow-x or overflow-y and something other than visible for the other, the visible value is interpreted as auto.

Answer 6

I used the content+wrapper approach ... but I did something different than mentioned so far: I made sure that my wrapper's boundaries did NOT line up with the content's boundaries in the direction that I wanted to be visible.

Important NOTE: It was easy enough to get the content+wrapper, same-bounds approach to work on one browser or another depending on various css combinations of position, overflow-*, etc ... but I never could use that approach to get them all correct (Edge, Chrome, Safari, ...).

But when I had something like:

  <div id="hack_wrapper" // created solely for this purpose
       style="position:absolute; width:100%; height:100%; overflow-x:hidden;">
      <div id="content_wrapper"
           style="position:absolute; width:100%; height:15%; overflow:visible;">         
          ... content with too-much horizontal content ... 
      </div>
  </div>

... all browsers were happy.
