height of textarea is too large

[Akihiro Motoki]

In Juno master branch, the height of textarea is 10 lines and it seems too large
when considering usecases of text areas in Horizon forms.
Especially in case where a forms has multiple textareas, e.g. "Create Network" workflow "Subnet Details" tab.

3~5 lines seems good to me.

I am not sure which is a preferred way.

(1) To set attrs rows in Django Textare.

  forms.CharField(widget=forms.Textarea(attrs={'rows': 3}),

or

(2) To set class in textarea attrs and define height in CSS.

    reduce the height of the textarea to 4

    Textarea of height 10 lines seems large considering the usecases
    in Horizon for forms containing multiple fields. Reducing it to a
    lesser value for subnet workflows in networks and images forms.
