When applying truncation, place the full text in a title attribute so that it’s accessible on hover. Note: There is an iOS bug that is triggered when you add a component from Visualforce into S1 using an iFrame. The truncated element does not recognize its width.
Truncation: Single Line
If problems occur when using truncation with elements that use flexbox, you might need to add the
.slds-has-flexi-truncate class on the flexbox child node (
.slds-col_padded elements) that contains the truncated text.
