 Comma-separated expressions are not allowed as attribute/directive values in runes mode, unless wrapped in parentheses
 ```
 
-```
 An attribute value cannot be a comma-separated sequence of expressions — in other words this is disallowed:
-```
 
-```
 ```svelte
 <div class={size, color}>...</div>
 ```
-```
 
-```
 Instead, make sure that the attribute value contains a single expression. In the example above it's likely that this was intended (see the [class documentation](class) for more details):
-```
 
-```
 ```svelte
 <div class={[size, color]}>...</div>
 ```
-```
 
-```
 If you _do_ need to use the comma operator for some reason, wrap the sequence in parentheses:
-```
 
-```
 ```svelte
 <div class={(size, color)}>...</div>
 ```
-```
 
-```
-[!NOTE] This will evaluate to `color`, ignoring `size`.
