Hi Paulo Torres,
Css need to send as input parameter same like as text.
For instance,
".Class1
{
background-color: #000;
font-size\:10px;
}"
and
send the html code like this
"<html>
<p>HI Hello Test </p>
<p class='Class1'> SAMPLE HTML CODE FOR TEST </p>
</html>"
try this..
May be for this error u need to check the html code u have send. Use ClassName for css and send the css code as input parameter as i mentioned above.
Thanks,
Vidya.U
