I have been trying to shrink the overall size of the big blue banner at the top of the home page. I need it to be just big enough to house the mission statement already written in it. In the past when I have tried to shrink the hight of it, the other pages within the website have gone askew, so I have had to restore it. Please help.Thank you to anyone who can help. Please note that I only have moderate experience in Stylesheet CSS and will need detailed instructions.
