Question: If I have 2 items with 1-1 strong dependency then one is an attribute i.e. column in the other one's table.  

E.g. if we have a movie database and each movie must have a review score (*review score is a number that represents the average score from X number of viewers*) and each review score belongs to a movie then the review score should be a column in the table Movie.  

Now if the review score comes from X number of people that actually did the review then this should be part of the Movie database too as a column.  

But seems weird to me because the number of people is an attribute of the review score not of the movie right?  

Am I misunderstanding something in this database design approach/theory?

Answer: 
Please try this

```
<h1 id="hover">Hover over me</h1>
<img id="squash" src="http://askflorine.com/wp-content/uploads/2013/10/temp_quash.jpg" width="100%">

#squash {
  display: none;
}

#hover:hover ~ #squash {
  display: block;
}

```
Depends on what you put in between the 2 parts. If text encase squash inside the  

```
<p> text here
    <div id="squash"...>
    </div>
</p>

```

Then css changes to

```
#hover:hover + p #squash {

```
