Here's why it's so nice to do it the CSS way:
- You only have to do it once. When you add your signature to your blog's CSS, it will automatically appear on every one of your blog posts.
- It's easy to change. If you decide to change your signature image, just change one line of CSS and the signature will update on every single post.
- No borders. When you add your signature image with CSS, it doesn't get the border that Blogger automatically adds to your post images.
- Pinterest-proof. Your readers can't accidentally Pin your signature if you add it with CSS. The Pinmarklet and the official Pin It buttons ignore CSS images.
