Я использую некоторые значки из SVG-спрайта, и это пример разметки HTML:
<svg class="feature__icon">
<use xlink:href="img/sprite.svg#icon-presentation"></use>
</svg>
Значки отображаются и работают очень хорошо в Chrome, но в Firefox они даже не отображаются.Я также попробовал это без xlink, так как это устарело, но это не проблема.У кого-нибудь есть идеи, как заставить его работать в Firefox?
Обновление: вот ссылка на файл спрайта, и я также включаю код здесь.
