Getting a horizontal scroll bar within a 100% div

I'm trying to build a quick overview that shows the upcoming calendar week. I want it arranged horizontally so it can turn out to be quite wide if we show a full calendar week.

I've got it set up right now with an inner div with a fixed width (so that the floated "day" divs don't return below) and an outer div that's set to width: 100%. I'd LIKE for the outer div to scroll horizontally if the page is resized so that the inner div no longer fits in it, but instead the outer div is fixed larger at the width of the inner div and the page itself scrolls.

Gah I'm not good at explaining these things... Here's a bit of code that might clear it up..

The CSS:

.cal_scroller {
    padding: 0;
    overflow: auto;
    width: 100%;
}

.cal_container {
    width: 935px;
}

.day {
    border: 1px solid #999;
    width: 175px;
    height: 200px;
    margin: 10px;
    float: left;
}

and the (simplified) structure:

<div class="cal_scroller">
    <div class="cal_container">
        <div class="day">Monday</div>
        <div class="day">Tuesday</div>
        <div class="day">Wednesday</div>
        <div class="day">Thursday</div>
        <div class="day">Friday</div>
    </div>
</div>

So to try again - I'd like the cal_scroller div always be the page width, but if the browser is resized so that the cal_container doesn't fit anymore I want it to scroll WITHIN the container. I can make it all work if I set a fixed width on cal_scroller but that's obviously not the behavior I'm going for. I'd rather not use any javascript cheats to adjust the width of the div if I don't have to.

I struggled with this a lot but the simplest solution I found was adding:

.cal_container { white-space: nowrap; }

This way you don't have to give it a width at al. It just makes sure everything stays in one line.

Your cal_scroller class is 100% + 20px (padding) wide. Use a margin on cal_container instead, like so:

.cal_scroller {
    padding: 10px 0;
    overflow: auto;
    width: 100%;
}

.cal_container {
    margin: 0 10px;
    width: 935px;
}

See here for a description of how the box model works (in short, the everything is outside the width/height of an element).

Also, block elements (like <div>s) are 100% width by default, making your 100% width declaration redundant.

I didn't read your question very carefully, but when you have width: 100% and padding, that's generally not what you want.

100% + 20px > 100% - that might be the problem.

One problem I see is your width: 100% rule. div.cal_scroller is already a block-level element, so it'll default to filling the entire page width. (Not to mention that padding is added on top of width, so you end up with that div being bigger than the page.)

Just get rid of that width rule, and you should be golden. (I just tried myself, and it worked like a charm.)
