Thanks Okoth1 for specifying where the proper line exists in rapid-twitter-widget.php
A different approach is to leverage css. This can be accomplished by modifying rapid-twitter-widget.php
:
was:
echo "<a href='" . esc_url( "https://twitter.com/{$account}" ) . "'>" . esc_html($title) . "</a>";
becomes:
echo "<a id='Rapid-Twitter-Custom1' href='" . esc_url( "https://twitter.com/{$account}" ) . "'>" . esc_html($title) . "</a>";
Also modify custom.css
such that the following is added (using whatever color you want):
#Rapid-Twitter-Custom1 {
color: rgb(51,51,51);
}
Good luck!
