When developing a Toolset based content template I think I have found another minor bug I am afraid. Same CSS button subject. In this case the button text color is inherited from the default theme color as defined under appearance>customizing>general settings>typography ....setting of body link color.
I think adding "!important" CSS addition can be the solution for the .tb-button__link { color:#xxxxx}
Test page dev site : hidden link
Question: do you have a quick fix for this? Until now I did not find one.
Can you check if it works when activating the "CSS selectors of Toolset Blocks" option in Toolset->Settings->General(tab) Check this screenshot hidden link
Otherwise, can you show me on the sandbox site this issue hidden link
