To edit how your Blog Title looks like go to Layout page in your dashboard and click Edit button on the Header gadget:
You can use Blog Title and Description fields to create your blog title. The font used in the template will be used automatically.
If you choose that, but would like to use a different font than the one originally used in the template or would like to change the size of the title or description – you can do that in the template Customize area. To get there, go to Layout page and click the Customize button.
There in the Template Designer Window choose an Advanced tab and click Blog Title:
You can choose a different font, modify font settings like font weight (bold) or font style (italics) and choose font’s size and color.
If at any time you want to bring back the default settings – simply click the blue link saying: Clear advanced changes to the blog title.
But maybe you want to use your own image for the blog title? That’s even easier! Come back to the Layout page of the dashboard and click Edit on the Header gadget. Below the blog title and description you will find options to upload your own image.
If the image should serve as a background to the title choose Behind title and description. If on the other hand you have a complete header ready and want to use it instead of the default setting, choose Instead of title and description.
