Hi
I’m trying to validate my webpage, but I’m getting a few errors.
My code:
```auto
```
The errors I’m getting:
Attribute “NAME” is not a valid attribute. Did you mean “name”?
Attribute “ID” is not a valid attribute. Did you mean “id”?
Attribute “CLASS” is not a valid attribute. Did you mean “class”?
Attribute “SRC” is not a valid attribute. Did you mean “src”?
Attribute “STYLE” is not a valid attribute. Did you mean “style”?
Attribute “FRAMEBORDER” is not a valid attribute. Did you mean “frameborder”?
element “IFRAME” undefined. Did you mean “iframe”?
The errors don’t really make any sence, because all my code is already in lowercase. What am I doing wrong?
