[Theme: Neni] Child theme css does not work

I am using the following code in a child theme:

/*
Theme Name:     Neni CT
Template:       neni
*/

@import url("../neni/style.css");

.test {
	color: #FF0000;
	font-weight: bold;
}

and the following code at the top of wp-content/themes/neni-ct/sidebar.php

<p class="test">This is test</p>

The paragraph displays on the web page, but it is not bold or red. I’ve made quite a lot of child the past, and I am working on about 20 at the same time, and dont have a problem like this one with any one of them.

Does anybody have an idea what might be going on?

Thank you.

EDIT: The child theme imports parent’s css, but the styles in it dont work.
