Today Blogger announced two new style for NavBar to match the style of NavBar with your blog’s theme. “Transparent Light” and “Transparent Dark.” These new color schemes take advantage of the ability of modern browsers to render transparency (a technique known to web designers as “alpha blending”). This allows the navbar background to blend together with your blog’s background color and pattern. The “Transparent Light” color scheme has a semi-transparent white background, producing subtle pastel colors, while the background of “Transparent Dark” is a semi-transparent black that produces a shaded look.

In addition, Blogger simplified and slimmed down the look of all the navbars, so that they will be more likely to harmonize with the aesthetics of your blog.

To enable the Transparent Light or the Transparent Dark navbar, go to Layout | Page Elements, then click Edit next to the navbar widget:
