you have to specify what you mean with red? if you're using css, define your class or ID div, and give it its properties.
if you edit/update your question, leave a reply so i get a notification. Your code is not visible, take the following steps to make it visible:
As you have not made your code visible, we cannot help you except give you our code so here's mine:
<!DOCTYPE html> <html> <head> <title></title> </head> <body> <p>This text is black, except for the word <span style="color: red">red</span>!</p> </body> </html>
That should work!
i had same error all you need to do is add the " " between the color:red. so ie
<p>This text is black, except for the word <span style="color: red">red</span>!</p>
