How to properly scroll on Safari mobile (iPad)?

Question

I need to handle both horizontal and vertical scrolling in a simple way, that works on Safari mobile in general and iPad in peculiar.

I have a very simple HTML/CSS framework which I wanted to keep very simple described as follows.

Horizontal scroller

Unfortunately, this requires I compute the width of the scroller, depending on the content. Is there an automatic way?

The HTML is as follows:

       <div class="scrollerContainer hScrollable">
            <div class="scroller">
                <div id="photo1"></div>
                <div id="photo2"></div>
                <div id="photo3"></div>
                <div id="photo4"></div>
                <div id="photo5"></div>
                <div id="photo6"></div>
                <div id="photo7"></div>
                <div id="photo8"></div>
                <div id="photo9"></div>
            </div>
        </div>

And the related CSS as follows:

.hScrollable {
    overflow-x: scroll;
    overflow-y: hidden;
    -webkit-overflow-scrolling: touch;
    white-space:nowrap;
}

scrollerContainer {
    -webkit-box-sizing: border-box;
    width: 100%;
    height: 50px;
    margin: 0;
    border: solid 1px black;
}
.scroller {
    -webkit-box-sizing: border-box;
    margin: 0;
    padding: 4px;
    white-space: nowrap;
    overflow: hidden;    /* Really important to avoid vertical scrolling on devices */
    width: 100%;
    height: 50px;
    background-color: lightgray;
}

.scroller>div {
    width: 50px;
    height: 50px;
    display: inline-block;
}

Vertical scroller

I'd like the content to fill the parent container, and is exceeding the vertical size, scroll vertically.

The HTML is as follows:

<div id="container" style="height:400px">

        <div style="height:100px">
           Fixed content, I dont want to vscroll
        </div>
        <div class="tabContent">
           Potentially long content that should vscroll. 
           This div should fill to the end of the container. 
           I don't want to set its height to 300px, 
           but to find a way it does automatically. 
        </div>

</div>

You had a bit TOO much css happening in there. I updated your fiddle with the properties I moved/removed.

I removed .hScrollable and .scrollerContainer from the css and added the overflow properties right to .scroller.

So .scroller now looks like this:

.scroller {
    -webkit-box-sizing: border-box;
    margin: 0;
    padding: 4px;
    width: 100%;
    background-color: lightgray;
    overflow-x: scroll;
    overflow-y: hidden;
    -webkit-overflow-scrolling: touch;
    white-space:nowrap;
}

Here's the fiddle.
