Hello ebhelloworld28,
If you want to make these changes at your Block Title, you should use a bt of CSS code to do that. Try the code below and place it in Theme panel->Custom CSS area
.block-title{
width:96%;
}
.block-title > span {
width:100%;
}
The result is here -> https://www.screencast.com/t/l3MCYtYbbB
Also, please notice that code work as properly if you will not use the Ajax Filter for your Blocks.
Thanks for the message!

Hello Cilene,
If you want to do this, you should use a bit of CSS code. Try the code below and place it in Theme panel->Cusotm CSS area.
The code is ->
body .block-title span{
background-color:green!important;
color:white!important;
}
This is a general code which can influence your entire website. For more information about how you can create your custom CSS rule using the web inspector browser you should check here -> https://forum.tagdiv.com/create-custom-code-using-the-browsers-inspector/
Thanks for your understanding!
