如何修改Widgets标签云的字体大小？稍微研究了一下，其实很简单，还是修改代码！我就是喜欢改代码，嘎嘎~

因为是修改Widgets标签云，所以目标文件依旧是wp-includeswidgets.php，打开并搜索wp_tag_cloud，这个就是标签云的调用函数了，查了一下参数表，得到wp_tag_cloud函数的参数如下：

smallest – Adjusts the size of the smallest tags in the cloud. Default is “8″.
largest – Adjusts the size of the biggest tags in the cloud. Default is “22″.
unit – Sets the unit type for font size (i.e. point or em). Default is “pt”.
number – How many tags will display in the cloud. Default is “45″.
format – “Flat” displays an inline cloud with each term separated by whitespace. “List” generates an unordered list. “Array” lets you define an array of tags. Default is “flat”.
orderby – Sort the cloud by “name” or “count”. Default is “name”.
order – Sort the cloud in ascending or descending order. Default is “ASC”.
