Still works after all these years

Amazing that this plugin still works despite not being updated for so many years. The only fix I had to make was adding a bit of CSS coded to remove the border and shadow on images. I got these updates on https://www.mikematera.com/make-your-wordpress-twenty-ten-theme-responsive/. I’ve put them in a code block below:
/* The following 3 entries fix problems with Responsive TwentyTen plugin.
They correct the appearance of shadows and borders on images
and (apparently) the header image doesn’t always automatically adjust to the screen size */

.entry-content img.size-full {
  border: none;
  padding: none;
  -moz-box-shadow: none;
  -webkit-box-shadow: none;
}
img {
  max-width: 100%;
  height: auto;
}

#content img {
  border: none;
  padding: none;
  -moz-box-shadow: none;
  -webkit-box-shadow: none;
}
/* End of 3 entries to correct Responsive Twenty Ten plugin. */

I’m going to use a responsive (hamburger) menu plugin of https://en-au.www.ads-software.com/plugins/responsive-menu/ just to make it more mobile compatible (I’ve been using this plugin for over a year with Twenty Ten theme) on another site.

I’ve tested this Responsive Twenty Ten theme on quite a few different types of pages and with many other plugins and it all seems to work fine. Thank you to the author.
