I haven’t…
It’s totally odd.

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

I don’t believe the error is there : all the other things i made in my theme child works.

<?php
remove_action( 'widgets_init', 'twentythirteen_widgets_init' ); //necessary to replace parent theme's code
function twentyten_child_widgets_init() {
register_sidebar( array(
'name' => __( 'Alt Primary Widget Area', 'twentyten' ),
'id' => 'alt-primary-widget-area',
'description' => __( 'Alt primary widget area', 'twentyten' ),
'before_widget' => '<li id="%1$s" class="widget-container %2$s">',
'after_widget' => '',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>',
) );
}
/** Register sidebars by running twentyten_child_widgets_init() on the widgets_init hook. */
add_action( 'widgets_init', 'twentyten_child_widgets_init' );

In fonctions.php (child)
It seems to work… i’ll make tries and see Thanks for your help

hum, yeah.
And how do i do that? (a tuto perhaps?)
And after… where i must declare this function?

when i made that (change child) i have errors and my website doesnt work anymore…

But perhaps i made it wrong.

If you use “twentythirteen_widgets_init() {” in a functions.php in your child theme, it doesnt work… what should i do?
