1) I have a page with content. 2) I have a hamburger menu which when clicked brings the off-canvas menu

I need:

To not be able to scroll my page with content when I am in the off-canvas menu. How to achieve that?

PS I can add the code if that is needed. But perhaps it is simple question for someone. Tell me if you need the code

Answer 1

you can set body overflow to hidden using javascript or jquery or add a class

CSS:

.scroll-off{
   overflow: hidden;
}

script:

$(body).addClass('scroll-off');

or

$(body).css('overflow', 'hidden');

for more information, you can read more about jquery in w3schools.com

Example:

 <html> <head> <title>title</title> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script> </head> <body> <button>Click Me</button> <div style="width: 300px; height: 1000px; background-color: red;margin: 0px auto;"></div> </body> <script> var index = 0; $('button').click(function () { if(index == 0){ $('body').css('overflow', 'hidden'); index = 1; }else if(index == 1){ $('body').css('overflow', 'auto'); index = 0; } }); </script> </html>

this is your file whit script code:
