How do I change the font color of a link element inside a box?



I have been struggling with it for a long time.



```



<td style="background: rgb(0, 0, 128); padding: 7.5pt; border: 1pt solid rgb(0, 0, 0); border-image: none; text-align: center;"><!--[if gte mso 15]><style type="color:#ffffff;"> </style><![endif]--><span style="color:rgb(255, 255, 255)"><span id="surveylink">${l://SurveyLink?d=Take the Survey}</span></span><style type="text/css">span#surveylink>a{color:#ffffff;}</style></td>



```



How to change this so that the link appears white?



Please help!
