under the iphone6 standard, I wrote a text tag in the view tag and set the font for text to be relatively small. I found that the view shows that view is actually one piece higher than the text tag. I don"t know whether the view tag has the default line height or height (I can"t see the default style of the tag in Wechat"s developer tool, who can teach me how to look at the default style of the tag). Ask God to tell view whether there is a default line height or a default height, and the code
<view>
<text style="font-size:24rpx;">aaa</text>
</view>
