Django 1.6: How to layout charfields in one row, without wasted space, in the admin panel

Question

I am having a spacing issue with Django 1.6 (Python 2.7.13 x86).

I have a version number in my program, and the spacing looks bad...

class SoftwareAdmin(admin.ModelAdmin):

    fields = ('name', ('version1', 'version2', 'version3'))

    form = SoftwareAdminForm

class SoftwareAdminForm(forms.ModelForm):


    version1 = forms.CharField(max_length = 2, label = 'Version:', widget = forms.TextInput(attrs = {'size':2}))

    version2 = forms.CharField(max_length = 2, label = '.', widget = forms.TextInput(attrs = {'size':2, 'title': '.'}))

    version3 = forms.CharField(max_length = 2, label = '.', widget = forms.TextInput(attrs = {'size':2, 'title': '.'}))


    version1.initial = '0'

    version2.initial = '0'

    version3.initial = '0'

So, what I want is these three char fields to look nicer, and to get rid of all the space in between; I want version1, version2, and version3 to all be flush and right next to each other. How can I do this? Thanks.
