Button button adaptive size of wechat applet

When I was working on the applet, I found , Can be in wxss Set borders , Color, etc . But when testing the screen size change , stay wxss Set in the width、height、font-size etc. , Buttons do not adaptively change size .

stay wxml Medium button Set as follows

size=“mini” type=“default” class=“pingjia” style=‘width:150rpx;font-size:30rpx !important;’

among style='width:150rpx;font-size:30rpx !important;' It can change the size of the button and the size of the text in it , Unit demand rpx, Will adapt to change , Only in style Set the width , font size ,button The button will change , stay wxss Invalid setting in .
