这个命名可以考虑下
// Size
.font-size-larger     { font-size: $font-size-larger !important; }
.font-size-large      { font-size: $font-size-large !important; }
.font-size-normal     { font-size: $font-size-base !important; }
.font-size-small      { font-size: $font-size-small !important; }
.font-size-smaller    { font-size: $font-size-smaller !important; }
// Weight
.font-weight-light    { font-weight: $font-weight-light !important; }
.font-weight-lighter  { font-weight: $font-weight-lighter !important; }
.font-weight-normal   { font-weight: $font-weight-normal !important; }
.font-weight-bold     { font-weight: $font-weight-bold !important; }
.font-weight-bolder   { font-weight: $font-weight-bolder !important; }


.font-inherit         { font:inherit !important; }__
