How to make triangle without background in css?

Question

css

Hello, please tell me how to make a triangle in css, with a transparent background like in the screenshot?

Answer 1

pull out the shape as svg or png :)

Answer 2

Don't fence the garden. CSS does not (yet) provide for triangles. You can dodge with the border or pseudo-elements, but this is done for very small triangles, where it is impractical to drag the icon.

for example

Без понятия, почему первая ссылка на китайском, но треугольники подходящие

And you have a whole button. Make SVG-shkoy and do not complicate life for yourself and others)
