Scriptless Social Sharing is a wee plugin to add buttons to your posts/pages, to make it easier for your readers to share your content on social networks.
The sharing links use the most basic methods provided by each network. There is no JavaScript, nothing fancy included in this plugin, so if you want fancy, this is not the plugin you’re looking for. It just builds a set of links.
The sharing buttons are accessible–even if you choose the “Icons Only” button styles, the network names are still part of the buttons, just hidden in an accessible-ready manner.
There is a small settings page, so you can make decisions about which content types should have sharing buttons and where, what buttons should be added, and whether or not to use the plugin’s styles. Beyond that, developers may like to make use of filters throughout the plugin.
