Adjust Search bar width?

Absolutely!

.navigation-search {
      width: 100%;
}

100% is the default - you can change that to pixels or whatever you like.

You rock! :)

Hi. I've tried adding this css and setting width to 50%, but on my site the navigation bar is aligned to the right and the search box ends up on the opposite side of the screen.

Here's my css:

.navigation-search {
      width: 50%;
}

and a screenshot of the settings:

What am I missing?

Any chance you can open a new topic and link us to the site in question with the CSS added?

Thanks :)
