    text-indent

    概述

    text-indent 属性 指定了 水平距离 should be left before the beginning of the first line of the text content of an element. Horizontal spacing is with respect to the left (or right, for right-to-left layout) edge of the containing block element's box.

    • 初始值 0
    • 适用元素 block containers
    • 可继承 yes
    • Percentages refer to the width of the containing block
    • 适用媒体 visual
    • 计算值 the percentage as specified or the absolute length, plus any keywords as specified
    • 可动画 yes, as a length, percentage or calc(); when both values are lengths, they are interpolated as lengths; when both values are percentages, they are interpolated as percentages; otherwise, both values are converted into a calc() function that is the sum of a length and a percentage (each possibly zero), and these calc() functions have each half interpolated as real numbers.
    • Canonical order the length or percentage before the keywords, if both are present. If several keywords are present, they appear in the same order as their appearance in the formal grammar.
