[Share] Add a Line on top/bottom of Text Block

We will use some CSS code to add line like this.

If you can't make it work, you can send link to page where you added Text Block, I can check easier.

#1. First, find ID of Text Block.

In my example it is: #block-yui_3_17_2_1_1719906734967_2500

Next, use this code to Custom CSS box.

#block-yui_3_17_2_1_1719906734967_2500 {
p {
    border-top: 1px solid #000;
    margin-top: 0px !important;
    margin-bottom: 0px !important;
    padding-top: 20px !important;
    padding-bottom: 20px !important;
}
p:last-child {
    border-bottom: 1px solid #000 !important;
}}
