For the background color - the fill property can be accessed like so   svgElement style fill     fff     To set the border color  do the same for the stroke property   Please refer to the W3C reference on SVG  as it s a broad issue

Built off the above but with dynamic creation and a vector image  not drawing   function svgztruck         tok     d path value       return tok     function buildsvg  eid         console log  building        var zvg    svg    eid      var vvg   eval  zvg        var raw   vvg         var svg   document getElementById  eid        svg setAttributeNS null  d   raw        svg setAttributeNS null  fill   green        svg setAttributeNS null  onlick   eid     style fill  FF0000        return      You could call with    lt img src    onerror  buildscript  gt    Now you can add colors by sub element and manipulate all elements of the dom directly   It is important to implement your viewbox and height width first on the svg html  not done in the example above   There is no need to make your code 10 pages when it could be one    but who am I to argue  Better use PHP while your at it   The inner element that svg builds on is a simple  lt svg lamencoding id parenteid gt  lt path id eid gt  lt svg gt  with nothing else

Your SVG must be inline in your document in order to be styled with CSS  This can be done by writing the SVG markup directly into your HTML code  or by using SVG injection  which replaces the img element with the content from and SVG file with Javascript   There is an open source library called SVGInject that does this for you  All you have to do is to add the attribute onload  SVGInject this   to you  lt img gt  tag   A simple example using SVGInject looks like this    lt html gt     lt head gt       lt script src  svg-inject min js  gt  lt  script gt     lt  head gt     lt body gt       lt img src  image svg  onload  SVGInject this     gt     lt  body gt   lt  html gt    After the image is loaded the onload  SVGInject this  will trigger the injection and the  lt img gt  element will be replaced by the contents of the SVG file provided in the src attribute

This is for  lt object gt  SVG and className is  svgClass   lt object class  svgClass  type  image svg xml  data  image svg  gt  lt  object gt    So JavaScript code is like this      change to red     document querySelector   svgClass   getSVGDocument   getElementById  svgInternalID   setAttribute  fill    red     To change svgInternalID you have to open SVG file which is plain  txt  ie image svg  and edit it   lt path id  svgInternalID

If it is just about the color and there is no specific need for JavaScript  you could also convert them to a font  This link gives you an opportunity to create a font based on the SVG  However  it is not possible to use img attributes afterwards - like  alt   This also limits the accessibility of your website for blind people and so on
