I implemented an SVG triangle using HTML:
path {
fill: red;
filter: drop-shadow(5px 3px 17px rgb(0 0 0 / 1));
}
<svg style="height: 36px; width: 100%; background-color: #EAEAEA ;" viewBox="0 0 436 217" preserveAspectRatio="none" class="Tagline-triangle is-red first triangle" fill="none" xmlns="http://www.w3.org/2000/svg">
<path class="triangle-shadow-downward" d="M0 0H436V217L0 0Z"></path>
</svg>
This setup creates a shadow effect like this: https://i.sstatic.net/5dJdp.png
The subtle shadow along the diagonal of the triangle shows up perfectly on Chrome and Firefox but unfortunately doesn't appear on Safari. Any ideas why this might be happening and how to resolve it?
