How do I apply tag conditionals when using wx.html2?

I put the conditional expression in {2}, {3} and try to put green in case of Ture and red in case of False. Is it possible to use SetForegroundColour to represent colors? If you run it, it will be None. Do you need another method?
I also tried background-image: url ('1.png'); to specify the background, it's a white background. When using <img scr = 1.png /> inside the body tag, an x display image error appears.

Solution

It was a bit hard to comprehend what do you want but here is the simplest example of conditional background change of HTML element using .format. Be advised, to modify example for Python 3. CSS snippet background-color can be used on any element that supports it such as your <th></th> elements. If you want to change the text color just use the color attribute. Same can be applied in your <style> section of the HTML code.

import wx
import wx.html2
class AppFrame(wx.Frame):
    def __init__(self, parent):
        super(AppFrame, self).__init__(parent)
        self.html_view = wx.html2.WebView.New(self)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.html_view, 1, wx.EXPAND)
        self.SetSizer(sizer)

if __name__ == '__main__':

    Test = True

    if Test == True:
        color = 'Green'
    else:
        color = 'Red'

    app = wx.App()
    frame = AppFrame(None)
    frame.html_view.SetPage("""
            <!doctype html>
            <html lang="ko">
              <head>
                <meta charset="utf-8">
                <title>HTML TEST</title>
                <style>
                  body{{
                    background-position: conter conter;
                    background-color:gold;
                  }}
                </style>
              </head>
              <body>
              <p>Normal text</p>
              </br>
              <p style="background-color:{0}">Conditionally changed background for Test={1}</p>
              </br>
              </body>
            </html>""".format(color, Test), "")
    frame.Show(True)
    app.MainLoop()
