Writing CSS style data to a page via ethernet shield

Ah! What a silly mistake, I forgot to close the tag as you say :slight_smile:

many thanks!

I'm now attempting to show a different button by reading the state of a pin, but.... its not working lol
Just added this in, but neither image is showing up. When starting up the pin will be low, so I thought that the else if statement would run, which should display the on button, then once on the if loop would run, showing the off button?

maybe I have made another silly error, can't work out

This is the addition:

if(A == HIGH)
          {
            client.println("<a href=\"/?lightAoff\"\"><img src='http://www.shedbass.com/dtokez/buttons/off2.png'></a>");
          }

          else if(A == LOW)
          {
            client.println("<a href=\"/?lightAon\"\"><img src='http://www.shedbass.com/dtokez/buttons/on2.png'></a>
");
          }

//simple button GET server code to control servo and arduino pin 5
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html
//for use with W5100 based ethernet shields
//Powering a servo from the arduino usually DOES NOT WORK.
