Is there a way to select one element, immediately following (or preceding) other by pure CSS?

Foe example, hide one of `<br>` in a `<br><br>` pair:

```
<p>text text <br><br>text text <br>text text <br><br>text text</p>
<p>text text <br>text text <br><br>text text <br><br>text text</p>
<p>text text <br><br>text text <br>text text <br><br>text text</p>

```

and get it prosessed in the end as:

```
<p>text text <br>text text <br>text text <br>text text</p>
<p>text text <br>text text <br>text text <br>text text</p>
<p>text text <br>text text <br>text text <br>text text</p>

```

`display: none;` appled for `br + br` or `br ~ br` don't work as described above.
