Usage
JavaScript
.svg
Parameters
This function does not accept any parameters. Is this incorrect?
Examples
HTML
<img class="svg" src="<?php echo get_template_directory_uri(); ?>/assets/img/logo.svg" />
Demo
Additional Notes
Notice that once the SVG in the demo is replaced it is possible to programmatically control the fill color (and change it on hover). <img> tags that call SVG images are not able to do that.
Exporting SVGs from Adobe Illustrator
It is recommended to export SVG images using the following settings, and then run them through SVGOMG. This will prevent conflicts in selectors when multiple SVGs are on a page! It is also strongly recommended to also save out an optimized transparent .png file at the same size.

jQuery('img.svg').each(function(){
let oThis = jQuery(this);
if ( oThis.attr('src').includes('.svg') ){
jQuery.get(oThis.attr('src'), function(data){
let theSVG = jQuery(data).find('svg'); //Get the SVG tag, ignore the rest
theSVG = theSVG.attr('id', oThis.attr('id')); //Add replaced image's ID to the new SVG
theSVG = theSVG.attr('class', oThis.attr('class') + ' replaced-svg'); //Add replaced image's classes to the new SVG
theSVG = theSVG.attr('role', 'img');
theSVG = theSVG.attr('data-original-src', oThis.attr('src')); //Add an attribute of the original SVG location
theSVG = theSVG.removeAttr('xmlns:a'); //Remove invalid XML tags
oThis.replaceWith(theSVG); //Replace image with new SVG
//Move alt attribute to title element within the SVG (title must be the first tag inside the <svg>)
if ( oThis.attr('alt') ){
theSVG.prepend('<title>' + nebula.sanitize(oThis.attr('alt')) + '</title>'); //Sanitized to prevent XSS
}
//Move the title attribute to the description element within the SVG
if ( oThis.attr('title') ){
theSVG.prepend('<description>' + nebula.sanitize(oThis.attr('title')) + '</description>'); //Sanitized to prevent XSS
}
}, 'xml');
}
});
