SyntaxError: invalid syntax.
It seems like you're trying to write a CSS selector for a class named "b" and set its font size property. In that case, the correct syntax would be:
```
.b {
font-size: [desired font size];
}
```
Replace `[desired font size]` with the value you want to set for the font size property, such as `16px`, `1.2rem`, or `2em`.
