Remove text underline links in 7.1

Does anyone happen to know why this is not working? I only need the underline links removed in certain areas, not the entire site. 

/*REMOVE UNDERLINE FROM LINKS 7.1*/
section[data-section-id="63f0c7e6e113f56b3b37256e"]{background-size: 0px !important;
text-decoration: none!important;}

You mean remove links underline on 63f0c7...section?

Yes! Thoughts?

I tried this for a block ID but still not working...

#block-yui_3_17_2_1_1676721093940_660029 .text-link {
  text-decoration: none;
}
