SDL_HINT_EMS...NVAS_SELECTOR(3)

✨ NAME ✨

SDL_HINT_EMSCRIPTEN_CANVAS_SELECTOR — bestie, this is the hint that lets you pick which CSS selector gets used for the "default" window/canvas 💅

okay so quick vibe check first: we're deep in the SDL3 FUNCTIONS manual, and this page is gonna be short but iconic, i promise 🫶

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_hints.h>

#define SDL_HINT_EMSCRIPTEN_CANVAS_SELECTOR "SDL_EMSCRIPTEN_CANVAS_SELECTOR"

look at that #define, no cap. the hint's actual string value is literally SDL_EMSCRIPTEN_CANVAS_SELECTOR — copy it exactly or it will NOT hit 😭

---

🦋 DESCRIPTION 🦋

so the whole tea is: this hint only applies to the emscripten platform. if you're not on emscripten, this is giving... nothing. it's not for you, babe 🙈

and listen — you gotta set this hint before creating a window. like, before. it's not a "oh i'll set it later" situation. the window needs to know what it is first, so set it up front, periodt 👑

it's the thing that tells SDL which CSS selector matches the canvas it should treat as the default window/canvas ✨

---

💜 AVAILABILITY 💜

this hint has been around since SDL 3.2.0. so if you're on something older, sorry bestie, it's not gonna show up to the party 💀

that's the whole page, she's tiny but she's main character energy fr fr 🎀
