Next, we conserve the color worth that's been passed in, or utilize the default color ifthere isn't one. We echo the big, multiline portion of SVG markup utilizing PHP's heredoc syntax(

beneficial for templating). Variables such as$ color When utilizing this syntax, are broadened. We make a couple adjustments to the SVG markup. Classes are designated to the color-changing aspects. Second, a design component is included simply inside the SVG component, stating the proper CSS guidelines and echo- ing the $ color.
