Can't acces custom CSS in customizer

I can’t see this option in my activello theme
Admin Area -> Appearance -> Customize -> Activello Options -> Other -> Custom CSS

There is no ‘Other’ option under the ‘Activello theme’ option. Need help.

Hello there,

I hope you are doing well today.

There is no other option in the customizer.
You can access custom css by going to Appearance > Customize > Additional CSS and the css can be added there.

I want to change width of the sidebar in activello theme. As replied in some previous topic, I tried using the given code in additional css, I don’t see any change in width even after saving the code. Can you help me please.

Hello there,

I hope you are doing well today.

You can use the following CSS code to change the width of the sidebar, but you also need to change the width of the blog section too.

/*Blog section width*/
.col-md-8 {
    width: 60%;
}

/*Sidebar*/
.col-md-4 {
    width: 40%;
}
