Hi,

I need some coding advice on making a visual rating scale accessible.

The design calls for a category to be rated followed by 5 shapes - some
active the others inactive - to indicate the rating out of 5. The rating
is never written as text: it's simply visual.

The simplest solution is to create five images, one for each rating level,
so we can put alt text on them indicating the value. In pseudocode,
something like:

Quality: <img src="3of5.svg" alt="three (of five)"

Now, the question.
Someone suggested that we could build the rating display out of css shapes,
so there's no graphic to load. It would look something like this:

Quality: [shape-on] [shape-on] [shape-on] [shape-off] [shape-off]

But, I don't see where I would put the text version of the rating, without
changing the visual presentation.

Anyone have any advice?

Whitney

Are the stars interactive? Can you click on them to set a rating?
If they’re not interactive, you could dynamically write the rating to an sr-only span tag after the ‘Quality’ label.

pseudocode: <p>Quality:<span class=’sr-only’>3 stars out of 5</span></p> [shape-on] [shape-on] [shape-on] [shape-off] [shape-off]

If they’re interactive it’s a tougher task, because the buttons themselves would need to be accessible.
Inline images is probably the only widely supported way to get that accomplished – basically using a sprite but not a css sprite.

Assuming it's all in a span and not interactive you can do <span
role="img" aria-label="3 out of 5">

I know that the graphics may look better, but from an accessibility
point of view they are just awful.

For the sake of an interactive rating you could use a select. and when
presenting non interactively, you could use a read only edit.

I often get book reviews from audible where they present the rating
using a series of 5 graphics, all of which have an alt of "Rating
value". To make matters worse, they present 3 different rating
categories, Over all, Story, and Performance. You can guess how
frustrating this gets listening to the screen reader repeat rating value
5 times between each category.

Don't confuse bad implementations with "graphics are awful" though.

That's clearly bad implementation on the part of the developers there.
If they must use 5 separate <img> elements, the best advice would be for
the first image to have an alt text relaying the overall rating (e.g.
alt="4 out of 5 stars") and for the remaining four images to have an
empty alt="".

The stars are not interactive so that's easier
I get it about making Sr-only text...is that better practice? I always wonder if there are others who would need it but have it hidden from them with this technique.

Hi David
We agree with you.  Trying to avoid exactly the experience you describe. And the css sprites actually look better.

As someone easily confused by icons, I would love text myself.
Usually the stars are images: when they are interactive, they're
a b*tch to hit with your fat fingers and when they aren't, they
turn to fuzzballs when you magnify text (this mostly an issue
when there are empty stars/shapes and the lines for those are
small, thin and light grey, making it hard to tell what the
total range is). This might not be an issue if these are created
with CSS shapes in em-sizing though, would be cool to check out
the result.

However usually the Graphics Overlord determines that There
Shall Only Be Stars.

If yours is softer than mine, then if you can convince on
visible text, that is nicer. Not everyone is a cognitive
Sherlock Holmes, and I don't care that GO's 14-year-old
daughter "easily understands what it means", she's not me.

CSS-based solutions with visually hidden sr-only text will generally not
work for sighted users with images disabled, unless you use some form of
detection to determine if images are indeed turned off, and modify the
CSS accordingly to show the sr-only text.
