| // For modern browsers |
| // 1. The space content is one way to avoid an Opera bug when the |
| // contenteditable attribute is included anywhere else in the document. |
| // Otherwise it causes space to appear at the top and bottom of elements |
| // that are clearfixed. |
| // 2. The use of `table` rather than `block` is only necessary if using |
| // `:before` to contain the top-margins of child elements. |

| // Heads up! v3 launched with with only `.hide-text()`, but per our pattern for |
| // mixins being reused as classes with the same name, this doesn't hold up. As |
| // of v3.0.1 we have added `.text-hide()` and deprecated `.hide-text()`. Note |
| // that we cannot chain the mixins together in Less, so they are repeated. |
