我自己解决了 ,方法如下:
The final code after removing default JS and CSS from the Blogger blog will look like this.
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html>
<html b:css='false' b:js='false' b:defaultwidgetversion='2' b:layoutsVersion='3' b:responsive='true' ......>
By using the above method, you can remove default JS and CSS from the Blogger blog.
