Quickly replace WP Contact Form 7 Loading Gif

WPCF7 is an amazing contact form plugin. Its simplicity makes it great if you prefer to control all the elements of a sites design yourself. One annoying thing about it is that the loading gif is extremely old and only plays well on white backgrounds. Here’s a single line of CSS to replace its outdated AJAX spinner with an SVG inline one.

.wpcf7 form .ajax-loader {
  background: url('data:image/svg+xml;utf8,<svg xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.0" width="16px" height="16px" viewBox="0 0 128 128" xml:space="preserve"><rect x="0" y="0" width="100%" height="100%" fill="#FFFFFF" fill-opacity="0" /><g><circle cx="16" cy="64" r="16" fill="#EBEBEB" fill-opacity="1"/><circle cx="16" cy="64" r="16" fill="#DDDDDD" fill-opacity="0.67" transform="rotate(45,64,64)"/><circle cx="16" cy="64" r="16" fill="#999999" fill-opacity="0.42" transform="rotate(90,64,64)"/><circle cx="16" cy="64" r="16" fill="#cccccc" fill-opacity="0.2" transform="rotate(135,64,64)"/><circle cx="16" cy="64" r="16" fill="#e1e1e1" fill-opacity="0.12" transform="rotate(180,64,64)"/><circle cx="16" cy="64" r="16" fill="#e1e1e1" fill-opacity="0.12" transform="rotate(225,64,64)"/><circle cx="16" cy="64" r="16" fill="#e1e1e1" fill-opacity="0.12" transform="rotate(270,64,64)"/><circle cx="16" cy="64" r="16" fill="#e1e1e1" fill-opacity="0.12" transform="rotate(315,64,64)"/><animateTransform attributeName="transform" type="rotate" values="0 64 64;315 64 64;270 64 64;225 64 64;180 64 64;135 64 64;90 64 64;45 64 64" calcMode="discrete" dur="720ms" repeatCount="indefinite"></animateTransform></g></svg>');
