Twenty ten menu subitems

You have problem with the CSS – the sub-item appears slightly below the main menu item, so on mouseout the item loses focus causing the sub-menu to disappear.

Try to find what’s pushing the submenus down.

But the css has not been changed.
What can i do? OR where to look at? I am new to this.

I’ve made a new menu and deleted the orignal. But still no effect.

This is the menu part of my css

[CSS moderated. All we need is a link to your site]

When i change or delete the position rule, it works. But then it looks very stupid. The black background is then the size of the total menu width.

Do not edit the Twenty Ten theme itself. First create a child theme for your changes. Or install a custom CSS plugin.

Why must i use a child theme? I always make a backup of the website. So when a changes / update has problems i but the backup back.

I just want to solve my menu problem.

A WordPress child theme is a theme that inherits the functionality of another theme, called the parent theme. Child theme allows you to modify, or add to the functionality of that parent theme. A child theme is the safest and easiest way to modify an existing theme, whether you want to make a few tiny changes or extensive changes. Instead of modifying the theme files directly, you can create a child theme and override within.
