Accessibility enhancements

[Jackleberry]

I'm trying to add a couple of accessibility features to a fork of react-infinite. What I'm aiming for is the following structure:

<div role="feed" aria-setsize="-1" aria-busy={true/false}>
  <div role="article"></div>
  <div role="article"></div>
  <div role="article"></div>
</div>

The important pieces here are that the role="feed" is the outer div and it directly contains the article divs (which are the children that I would pass in to react-infinite).

At the moment this is not possible because there is a nested div that sits directly inside the outer div and that nested div contains the children. This is from the react-infinite.jsx code:

<div
        className={this.computedProps.className}
        ref={c => {
          this.scrollable = c;
        }}
        style={this.utils.buildScrollableStyle()}
        onScroll={this.utils.nodeScrollListener}
      >
        <div
          ref={c => {
            this.smoothScrollingWrapper = c;
          }}
          style={infiniteScrollStyles}
        >

I would like to remove this nested div and apply infiniteScrollStyles to the outer div and then I would be able to implement the structure as above.

My question is, do you see any issue in removing that nested div? From what I can tell and from testing it locally, it should be fine.

It should be fine in your fork if it works. The smooth scrolling wrapper no longer seems to be used.

@garetht Would you be interested in a PR into the main repo for this stuff?
This would be the PR if you're interested: #245
