<link rel="icon" href="data:;base64,iVBORw0KGgo=">
If your website/web app doesn’t use a favicon, then add the above code in your
<head>. This is because even if you don’t use a favicon, the browsers usually make a network call to get a
favicon.ico in the root directory, and preventing that network call can save your website around 20 ms.
Here’s how you should (or can) do a sticky CSS Footer.
Assuming the HTML looks something like this (and everything non footer is inside the “content” div)
<div class="content"> </div>
The easiest way to make the footer stick to the bottom would be to use some CSS like
margin: 0; /* If not already reset */
min-height: calc(100vh - 20px);
This makes the “content” div take the minimum vertical height of the entire screen, minus 20 pixels (the fixed height of the footer).
Most of the search results when Googling “sticky CSS footer” are half a decade old, but this is how a sticky CSS footer should be easily implemented in 2016.
