The theme is very beautiful (the color scheme and the graphics were very well done), and the content is well organized and easy to read, except I agree with chaaban on the subject of your invalid XHTML.
I ran your page through the W3C validator again, with the following result:
Result: Failed validation, 54 errors
Your CSS at https://jax.cacrew.com/wp-content/themes/green-bottle/style.css appears to be valid, however.
And also, make sure that your CSS validation link in the footer points to stylesheet in your theme folder, since it currently (and erroneously) points to a style.css in the root directory.
