The Code tab in Customizer
You can add HTML, CSS or JavaScript code into various locations within the HTML page that the Beaver Builder Theme generates.
Javascript code​
Javascript entered in this area will be rendered within <script> tags right before the closing <head> tag on every page, so don't include the <script> tags when you paste in code here.
Head code​
HTML, CSS, or Javascript entered in this area will be rendered in the <head> tag on every page. If you insert JavaScript into this section, include the <script> tags. This is the place to paste Google Analytics code.
Header code​
HTML, CSS, or Javascript entered in this area will be rendered directly after the opening <body> tag on every page.
Footer code​
HTML, CSS, or Javascript entered in this area will be rendered directly before the closing </body> tag on every page.
