Question: I am trying to make my nav bar sit parallel with my logo but I'm having difficulty doing this.

First of all, when I enter the code for the image, the image afterwards doesn't display at the top of the page. 

Instead, it sits about 40px below the page. I have tried using floats, but have had no luck. 

I have created a negative value of -20px for the logo to sit further at the top of the page but would like to know if that is normal practice in CSS

I have tried looking at youtube videos but the code they share doesn't seem to work on my project. I'm just wondering whether the image may be a bit too big for the header

Answer: 
"To maintain the integrity of the data dictionary, tables in the SYS schema are manipulated only by the database. They should never be modified by any user or database administrator. You must not create any tables in the SYS schema."

Try to put in this order:

```
ALTER TABLE table_name DROP COLUMN column_name;

```

If the table has data it doesn't work.
