A slider, with scripted output
We've seen <input type=range> earlier in this chapter. Notice
that, by default, browsers show the slider, but don't give any
indication of the minimum, maximum, or current value of the
slider, so let's code up an example that actually shows the user
the range allowed by the slider by automatically indicating the
minimum and maximum values, and dynamically outputting the
slider's current value.
The slider will go from 1 to 11, as all good controls should (be
they for guitar amps or otherwise). The step will be 1, which is
the default, so we can omit that attribute:
<input type=range min=1 max=11 name=tap>
To s h To w t h e u s e r t h e m i n i m u m a n d m a x i m u m v a l u e s , w e
can use generated content (which doesn't work on sliders in
WebKit browsers):
input[type=range]::before {content: attr(min);}
input[type=range]::after {content: attr(max);}
This will show the values, and style them as defined in CSS.
For example, Figure 3.12 renders
input[type=range]{width:500px; color:red; font-family:
¬ cursive; font-size:2em;}
