When you have your style between the tag and you want it to be the same for any link you change, you only have to copy/paste the code and change the href=“link.com” :
this is the old one:
$w("#Text").html = '<a style="color:red;font-size:20px" href="http://link1.com" >Stunning web sites</a>';
New link with same style :
if( today's date === 30-May-2018) {
$w("#Text").html = '<a style="color:red;font-size:20px" href="http://link2.com" >another website</a>';
}
