Fixing Transparent Sidebar

Hello,

I have been playing around with the theme and made the sidebar transparent, but when I do you still see a few shadows. How would you remove these? I have attached a picture to show.

Thanks in advance!

Here is the CSS I am using:

.well {
  background-color: transparent;
  padding: 0;
  border: none;
}
#secondary .widget {
  background-color: none;
  padding: 10px;
  color: #333;
  border: transparent;
  overflow: hidden;
  clear: both;
}

Update: I got it!

This is the code for those who are wondering:

.well {
  background-color: transparent;
  padding: 0;
  border: none;
  box-shadow:none;
}
#secondary .widget {
  background-color: none;
  padding: 10px;
  color: #333;
  border: transparent;
  overflow: hidden;
  clear: both;
}
