Bricks has a few handy action hooks that can be used to inject/add code in various areas of your websites.
Here are a few commonly-used ones.
bricks_meta_tags
To add code as high in the head as possible.
Screenshot from WPCodeBox:


wp_head
To add code before closing head tag.


bricks_body
To add code after the opening body tag.


bricks_before_site_wrapper
To add before the site wrapper. This one is above bricks_before_header and is redundant for practical purposes.

bricks_before_header
To add before or above the header.
Same screenshot as above.
bricks_after_header
To add after or below the header.

bricks_before_footer
To add before the footer.

bricks_after_footer
To add after the footer.

bricks_after_site_wrapper
To add after the site wrapper. This hook is below or after the bricks_after_footer hook.
Generally speaking, this is redundant or not necessary.
Same screenshot as above.
wp_footer
To add code before the closing body tag.
