Myth 2. Multiple class syndrome Note that class can be applied to any number of elements on the page, which is very suitable for identifying content types or other similar items

1 2 3 4 |
|

## class name news to identify the entire news item. Then you can use the cascade style to identify news titles and texts. You should modify it as follows1 2 3 4 5 6 |
|
span to group or identify the inline elements
