This is not specific to any particular theme, but handy for the floating that you’re after:
You can use a bit of an undocumented cheat in your markdown image code to float images left or right:
![](/image.png#floatleft)
to float left.
Or if you use figure shortcode: {{% figure src="/image.png#floatleft" caption="blah blah" %}}
![](/image.png#floatright)
to float right.
Or if you use figure shortcode: {{% figure src="/image.png#floatright" caption="blah blah" %}}
And then handle in your CSS as follows:
img[src$='#floatleft']
{
float:left;
//etc. etc/
}
img[src$='#floatright']
{
float:right;
//etc. etc.
}
