I did try that as well, now I have tried differents things, when I insert an H1 tag just before the logo, I can see the H1 text in the browser, but with no background color…:
Looking at your src attribute it looks like you are going back one directory and then re-entering the teasite directory. But I can’t see the name of your project directory from the screenshot. Since your index.html looks like it is already in the main project directory it would be better to use a relative path from the main project directory (where the one dot . simply refers to current directory):
"./images/img-tea-cozy-logo.jpg"
It does not seem necessary to go back a directory in this case with two dots looking at the file-structure. VS Code will also typically start showing available directories and file-names when typing in the src-path so that is a good feature to use to avoid broken links.
Also, I don’t see a link to the css-file in the VS Code screenshot of index.html. Make sure you include a link to the .css file up in the head for the css to work.
