Creating polygons with borders in HTML and CSS

I have spent the better part of the day trying to come up with a robust way to create polygons with a consistent border on HTML / CSS. I have tried 4 different methods so far which are all pretty inadequate. which can be found here: https://jsfiddle.net/op78fv6n/84/ Can someone help me figure out how to do this in a sane way?

the 'nesting issue' is more that i have to manually figure out how to position any content i want inside the shapes for some context, im trying to make a UI that allows people to define some polygons and then put text on top of them so it would be preferable if i could figure out the default paddings computationally

svg has <polygon> and also <text>

<svg width="240" height="240">
<polygon fill="lime" stroke="blue" stroke-width="5" points="0,0 100,0 150,50, 50,50" />
<text stroke="black" stroke-width="1" x="50" y="30">hello</text>
</svg>

<svg width="240" height="240">
<polygon fill="lime" stroke="blue" stroke-width="5" points="0,0 100,0 150,50, 50,50" />
<text stroke="black" stroke-width="1" x="50" y="30">hello</text>
</svg>

see here for how polygon works: https://www.w3.org/TR/SVG2/shapes.html#PolygonElement

is there a good way to make sure the stroke width stays consistent in x and y?

andersgee•2y ago

they are consistent, I just made it quickly, the polygon is at top y=0 so the stroke is "clipped". just move the polygon down points="0,20 100,20 150,70, 50,70" for arbitrary html you would probably need to wrap it in a position relative div and put things on top, something like

<div class="relative">
<svg class="absolute" width="240" height="240">
<polygon fill="lime" stroke="blue" stroke-width="10" points="0,20 100,20 150,70, 50,70" />
</svg>
<div class="absolute-polygoncontent">
  <button>
    some button or whatever
  </button>
</div>
</div>

<div class="relative">
<svg class="absolute" width="240" height="240">
<polygon fill="lime" stroke="blue" stroke-width="10" points="0,20 100,20 150,70, 50,70" />
</svg>
<div class="absolute-polygoncontent">
  <button>
    some button or whatever
  </button>
</div>
</div>

im sorry. in my original fiddle i could have sworn that the svg was getting compressed in y and not in x which made it look like the stroke width was thinner on top / bottom than it was on the sides im looking at the fiddle now and im not sure what changed.... but thats not the case now interesting ok. i think ill give svgs a try then thank you very much

andersgee•2y ago

wow sorry I didnt see you actually already tried svg in your fiddle, anyway glad to help
