I right-click on the webpage in the Firefox browser, and click on "view source code". Then I see the HTML source code. Some characters are in red color. I wonder what is means. Why dos the red-color characters mean? Does it mean that the source code is error in grammer? I don't think so. But the slash in the label <br /> is in red color. I wonder what is happening.

The red color only means that it's a bit special and the red color makes it easier to see. It does not mean that it's an error in the grammar. To see the errors and the warning you can open the errorconsole. On my computer I can press Ctrl+Shift+J or use the menus to open the errorconsole .
