We were having issues implementing lazy-loading on our D7 website. After a few failed attempts we discovered another method that we were able to implement.
In real world testing it appears to our eyes to defer the image loading. However, Google's PageSpeed Insights does not credit us with having deferred images. Here is a run test: (I had to remove the link in order to pass the SPAM filter)
Here is the img src we implemented (we altered the original white pixel and turned it gray b/c it helped us spot images in our TinyMCE editor rather than look at blanks):
We just spent the whole day investigating and sending out contact requests to Drupal developers, trying to find someone who can help us wrap up some issues with our site involving speed (we want the fastest possible speeds and we've run out of ways to improve any further), mobile friendliness, leftover garbage from a multi-site installation, etc.
With the Search API (version 7.x-1.26; we do not have Solr) search view, is there any way to link directly to search results beginning with the letter A, B, C, D, etc? I see the option to create a separate Glossary view but would like to avoid that if possible.
