Vigezo vya spinner za mpaka:

  --#{$prefix}spinner-width: #{$spinner-width};
  --#{$prefix}spinner-height: #{$spinner-height};
  --#{$prefix}spinner-vertical-align: #{$spinner-vertical-align};
  --#{$prefix}spinner-border-width: #{$spinner-border-width};
  --#{$prefix}spinner-animation-speed: #{$spinner-animation-speed};

  --#{$prefix}spinner-vertical-align: #{$spinner-vertical-align};
  --#{$prefix}spinner-animation-speed: #{$spinner-animation-speed};
  --#{$prefix}spinner-animation-name: spinner-grow;

Kwa spinner zote mbili, madarasa madogo ya kurekebisha spinner hutumiwa kusasisha thamani za vigezo hivi vya CSS inapohitajika. Kwa mfano, .spinner-border-smdarasa hufanya yafuatayo:

  --#{$prefix}spinner-width: #{$spinner-width-sm};
