Where to add the style attribute. i know that i should add it before th but how???
On line 11 you need to add color using style.
have a look at line 13 how the style is added, now you need to add style with the attribute color and value red
Try it, if you still get an error paste in your code and I will help you
a opening tag can have multiply attributes (style and colspan are both attributes), you simply separate them with a space, here is an example of a image with 2 attributes:
<img src="url" alt="my image">
hopefully, you can use this knowledge to add the style attribute
