Make header logo wider

I want to make the header logo wider than it currently it.
I have tried to read up several of the posts on this but it is still not clear to me how to make the logo container wider.
Can someone give me simple instructions for this?

Hey there,

I hope you are well today and thank you for your question.

Can you provide me with the URL for your website, so I can provide you with some CSS

Best regards,

Hi There

I am developing the site on the new server for it and the hosts file on my PC has been changed to point the IP address to the site:-

However before the client signed up I put an example site for them here:-

Does that help?

Currently the logo image is 525px wide and I would like it to be 800px, but once I know how to change I can experiment with sizes.

Hello there,

I hope you are doing well today.

The width already seems to be set to 858px however you can use the following CSS code to - by going to Appearance > Customize > Additional CSS and pasting it there.

/*Logo image*/

div#logo img {
    height: 100px;
    width: 800px;

img {
    height: auto;
    max-width: none;

Best Regards,
