I actually added this line to my html style=”border:none;” and it removed the border. Thank for your jelp jonrlipon. I really appreciate it!

Thanks Jomarlipon.
So how do I create the class?
Do I add the line as below in style.css? If so I did that, and save style.css
.img-border-black {border: 3px solid #000;}
.img-no-border{border:none;}

then I changed the html coded to
<img class=”img-border-black” src=”https://smarthomeworks.com.au/wp-content/uploads/2015/09/descines_domotique-control4-all-1024×643.jpg&#8221; alt=”” />

But my border is still gray. See pagee(and code at) https://smarthomeworks.com.au/control4-home-automation

What should I do? Or what am I doing wrong?
