[Documentation v3] Icons - Coloring - Examples are not correct?

[DAnn2012]

On the documentation page of framework7 v3.4.0 about the icons: http://framework7.io/docs/icons.html

In the section "Coloring" there are the following examples that do not work:

<i class="f7-icons color-red">home</i>
<i class="f7-icons color-yellow">home</i>

Instead, they only work if written like this:

<i class="icon f7-icons color-red">home</i>
<i class="icon f7-icons color-yellow">home</i>

Perhaps the examples are not updated to the latest versions of framework7?

Thanks.
