Cleaner way to use HTML SVG elements? - html

Question

I have several SVG elements that are under various HTML elements. As you can see in the example below they take up a lot of space and clutter the html.
I'm wondering if anyone has any suggestions on the best way to clean this up. I could use partial HTML views for each SVG element, but that's a bit overboard and all I can think of.
<div id="canvasControl" class="cnvsControl" hidden="hidden" style="height:36px; background-color:black; position:relative;margin-top:-36px;z-index:9999;opacity: 0.2;">
<div class="imageUpload canvasControlButton alignLeft" style="height:36px; position:relative;" title="Open File" id="btnOpenFile" name="btnOpenFile" onclick="snes_readfile(this)">
<label for="btnFileImport" style="position:absolute;top:5px;">
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="25" viewBox="0 0 512 512">

Answer 1

You can create a separate the SVG file and then link it to your HTML document like this:
Create SVG files named
one.svg :
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="25" viewBox="0 0 512 512">
<g id="icomoon-ignore"></g>
<defs>
<path id="openFolder1" d="M416 480l96-256h-416l-96 256zM64 192l-64 288v-416h144l64 64h208v64z"></path>
</defs>
<use fill="#fff" xlink:href="#openFolder1"></use>
</svg>
two.svg
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="25" viewBox="0 0 512 512">
<g id="icomoon-ignore"></g>
<defs>
<path id="outFullArrow1" d="M512 0h-208l80 80-96 96 48 48 96-96 80 80z"></path>
<path id="outFullArrow2" d="M512 512v-208l-80 80-96-96-48 48 96 96-80 80z"></path>
<path id="outFullArrow3" d="M0 512h208l-80-80 96-96-48-48-96 96-80-80z"></path>
<path id="outFullArrow4" d="M0 0v208l80-80 96 96 48-48-96-96 80-80z"></path>
</defs>
<use fill="#fff" xlink:href="#outFullArrow1"></use>
<use fill="#fff" xlink:href="#outFullArrow2"></use>
<use fill="#fff" xlink:href="#outFullArrow3"></use>
<use fill="#fff" xlink:href="#outFullArrow4"></use>
</svg>
three.svg
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="25" viewBox="0 0 512 512">
<g id="icomoon-ignore"></g>
<defs>
<path id="outArrow1" d="M512 0v208l-80-80-96 96-48-48 96-96-80-80zM224 336l-96 96 80 80h-208v-208l80 80 96-96z"></path>
</defs>
<use fill="#fff" xlink:href="#outArrow1"></use>
</svg>
Then edit your HTML to :
<div id="canvasControl" class="cnvsControl" hidden="hidden" style="height:36px; background-color:black; position:relative;margin-top:-36px;z-index:9999;opacity: 0.2;">
<div class="imageUpload canvasControlButton alignLeft" style="height:36px; position:relative;" title="Open File" id="btnOpenFile" name="btnOpenFile" onclick="snes_readfile(this)">
<label for="btnFileImport" style="position:absolute;top:5px;">
<object>
<embed scr="one.svg">
</object>
</label>
<input id="btnFileImport" type="file" onchange="snes_readfile(this)" />
</div>
<button class="canvasControlButton alignRight" title="Full screen" id="btnFullScreen" name="btnFullScreen">
<object>
<embed scr="two.svg">
</object>
</button>
<button class="canvasControlButton alignRight" title="Bigger Screen" id="btnChangeScreenSize" name="btnChangeScreenSize">
<object>
<embed scr="three.svg">
</object>
</button>
