在统计语言表达上，如果p值小于0.01，则称作0.01水平显著，例如，研究人员分析X对Y是否存在影响关系时，如果X对应的p值为0.00（由于小数位精度要求，展示为0.00），则说明X对Y存在影响关系这件事至少有99％的把握，统计语言描述为X在0.01水平上呈现显著性。

p:first-child { font-size: 115%; // Will set the font size to be 115% of the original font-size for the p element. } However, this will change the font size of every p element that is the first-child of any other element.
