如何使用Bootstrap4顯示和隱藏元素
為了更快地進行移動設備開發，請使用響應式顯示類來按設備顯示和隱藏元素。避免創建相同站點的完全不同版本，而是相應地為每個屏幕大小隱藏元素。
要隱藏元素，只需使用.d-none類或其中一個.d-{sm,md,lg,xl}-none類進行任何響應式屏幕變化。
要僅在給定的屏幕尺寸間隔上顯示元素，您可以將一個.d-*-none類與一個.d-*-*類組合在一起，例如，.d-none .d-md-block .d-xl-none將隱藏所有屏幕尺寸的元素，中型和大型設備除外。
Show/hide for breakpoint and down:
- hidden-xs-down (hidden-xs) = d-none d-sm-block
- hidden-sm-down (hidden-sm hidden-xs) = d-none d-md-block
- hidden-md-down (hidden-md hidden-sm hidden-xs) = d-none d-lg-block
- hidden-lg-down = d-none d-xl-block
- hidden-xl-down (n/a 3.x) = d-none (same as hidden)
Show/hide for breakpoint and up:
- hidden-xs-up = d-none (same as hidden)
- hidden-sm-up = d-sm-none
- hidden-md-up = d-md-none
- hidden-lg-up = d-lg-none
- hidden-xl-up (n/a 3.x) = d-xl-none
Show/hide only for a single breakpoint:
- hidden-xs (only) = d-none d-sm-block (same as hidden-xs-down)
- hidden-sm (only) = d-block d-sm-none d-md-block
- hidden-md (only) = d-block d-md-none d-lg-block
- hidden-lg (only) = d-block d-lg-none d-xl-block
- hidden-xl (n/a 3.x) = d-block d-xl-none
- visible-xs (only) = d-block d-sm-none
- visible-sm (only) = d-none d-sm-block d-md-none
- visible-md (only) = d-none d-md-block d-lg-none
- visible-lg (only) = d-none d-lg-block d-xl-none
- visible-xl (n/a 3.x) = d-none d-xl-block
