Child theme works, but doesnt show any changes

Hi there,
I am using elegant theme “chameleon”. I have created a child theme, and activated it. It is displaying the website, just like it did when I was using the parent theme. I was able to create a new menu in the child theme, and the changes show up just fine, however, any of the style changes I try to make have no effect, nor do the template changes.

Below is my style.css code:

/*
Theme Name: Chameleon_child_theme
Template: Chameleon
*/
@import url(“../Chameleon/style.css”);

.form-allowed-tags {
display:none;
}

Can anyone tell me what I am doing wrong? I have scoured the web and cannot seem to find the answer.
Many thanks in advance.
Jason
