SliderImageNav (buttons) u.MediaSlider

UI Questions

Hi,

I've created a site using the business template with the standard u.media slider installed, i've made a few changes to the layout and image sizes etc but i am having trouble with the image nav bar (the little buttons that let you move to different images in the slider). I cannot seem to get the nav button to appear on top of the images, its always behind which mean its not even visible to the end user.

I've tried z-index but this has no effect, can anyone help?

I'll add my CSS for the slider, please forgive me if its not very good, i am new to this.

thanks in advance

#imageshadow {
position:relative;
bottom:100px;
}

#slider {
  position:relative;
bottom:40px;
  overflow: hidden;
  width: 960px;
height:430px;
  clear: both;
  overflow:visiabl

}

  #slider .imageSliderInfo{
  color: #FFF;
  width: 960px;
  height:50px;
  position:relative;
  top:320px;
  background-color:#000;
  }

  #slider .imageSliderInfo h2{
  color: #FFF;
  font-size: 26px;
  }

  #slider .imageSliderInfo p{
  color: #FFF;
  font-size: 20px;
  padding:10px;
  }

  #slider .imageSliderImage{
  position:relative;
  bottom:110px;
  height:380px;
  }

  #slider .imageSliderImage img{
  border: 0px #000 solid;
  }

#slider #imageSliderNav{
  position:relative;
  bottom:0px;
  float: left;
  overflow: auto;
  text-align: left;
  width: 540px;
  padding-top:45px;
  padding-left:16px;
  }
  #slider #imageSliderNav a{
  background-image: url(/images/imageSliderNav.png);
  background-position: center center;
  background-repeat: no-repeat;
  background-color: #dee4e4;
  text-indent: -9000px;
  display: inline-block;
  height: 20px;
  width: 20px;
  }
  #slider #imageSliderNav a.activeSlide{
  }

Hi. I haven't looked into your CSS carefully, but as a first thought - did you account the thing that z-index works only for positioned elements?

Hi, thanks for your reply.

I have everything set to position:relative; and i've been using the left: right: top: bottom: method for posistioning things, is this the issues do you think?

Thanks

Dominic, try and remove "overflow:hidden" from
```
#slider {
  position:relative;
bottom:40px;
    overflow: hidden;
  width: 960px;
height:430px;
  clear: both;
  overflow:visiabl
}
```
and situation will become much clearer.

The slider nav is actally there, but it went down and "overflow:hidden" of the parent div hid it.

Oh. I have tried and it seems that all you need is just to add
```
#imageSliderNav {
  position: relative;
  top: -64px;
  z-index: 100;
}
```
to the end of an original custom.css file. Than you'll just need to edit the button png image and modify some background colors to maintain proper transparency.

wow thanks alot!!

i've put it in like this and its now on top and in the top left of the image

#slider #imageSliderNav {
  position: relative;
top: -455px;
  z-index: 100;
}

  #slider #imageSliderNav a{
  background-image: url(/images/imageSliderNav.png);
  background-position: center center;
  background-repeat: no-repeat;
  background-color: #dee4e4;
  text-indent: -9000px;
  display: inline-block;
  height: 20px;
  width: 20px;
  }

How does this work? I was told never to use minus figures in CSS. Glad it works tho, its been driving me mad for ages now. Thanks again!!!

That's simple. Simply, position: relative means that everything is ok but you just want somehow to shift the element from the 'normal' flow. In your case you just take your #imageSliderNav and shift it upside by "top: -NNN". It's strange to hear about avoiding usage of negative values in CSS since they're very important for some standard methods. For instance, look at the following (i think most-known) method of building transparent rounded corners:

It's completely based on negative margins.

Well it was my boss that told me that, he is a silverlight dev man with basic CSS skills, maybe thats why hehe

fyi, for rounded boarders i've been using:

border: 1px solid #696; padding: 60px 0; text-align: center; width: 200px; -webkit-border-radius: 100px; -moz-border-radius: 100px; border-radius: 100px; background: #EEFF99; behavior: url(/PIE.htc);
