Still seeing all black, unless I remove CSS code block for overlay.

I get a black screen on refresh every time. The only way I see to remove this is by deleting the CSS styling for the overlay. That's not covered in the video.

Once I remove the CSS, I get the image to appear, but the overlay isn't covering the rest of the screen. (It's there, but since it's unstyled, it's invisible.)

What am I missing? Is this a browser cache problem?

Hi Ryan,

Can you post your code here so we can take a look? Otherwise it would just be guessing.

Ensure you have the rgb ALPHA set to 0.7 like it states... it should look something like...

$("#overlay").css("background-color", rgba(0,0,0,0.7));

rgb(0,0,0) is a black and if you have a fourth value it becomes the transparency, 0.7 says 70% and so it becomes 70% transparent else it will be pure black.

with out seeing the CSS for the overlay this seems to be the most logical issue with your code.

Hey Ryan,

I also had some issues with the "background: rgba" CSS style as well. What ended up working for me was making sure there was no space between the "rgba" and the values.

e.g.

working code:

```background: rgba(0,0,0,0.7);

broken code:

```background: rgba (0,0,0,0.7);

I hope this helps with your overlay problem as well.

Good luck!
