I've written down exactly what I've done:
Visual web developer – new project - New web application
Double click "Site.Master" in solution explorer.
Click "design"
Select the text: "My ASP.NET Application"
Format – font - change color - (not showing change. Opening font again shows the old font color.) Why?
Click on "<h1.style1>
" at bottom
Format – font - change color – (this time it works fine)
Click to the right of "My ASP.NET Application" – div.loginDisplay is selected. Why? Why not the whole header?
Change background color - "My ASP.NET Application" disappears. Why? <- My main question.
Start debugging – "My ASP.NET Application" is shown. Why (since it wasn't showing in visual web developer)?
