我需要帮助创建一个可以随不同屏幕大小/设备而缩放的边框。我已经附上了期望的结果、我目前编写的html/css和一个预览结果的实时页面。
问题/疑问:
- 边框是使用像素设置的,我担心它在不同的设备/浏览器上不能按比例缩放。
- 四个角不太匹配。
- 有没有更好的方法来实现所需的边框,以便按比例缩放并实现所需的角落格式?也许是矢量图像?
我接近实现匹配,但肯定有一种(更简单?更好?)的方式来重新创建那种类型的边框。非常感谢您查看此内容并提供意见。
问候,
Zephyr
编辑/更新:
我还尝试使用background-image:
,并创建了六个.png文件,每个文件都有一个纯白色背景,分别用于"边框"的每个角落,以及用于"边框"的上下和左右两侧。同样,这很接近,但图像不总是正确对齐。
肯定有一种方法可以做到这一点,也许是在一个svg图像中,根据其所在部分的大小自动缩放,但这远远超出了我的能力范围。
感谢您考虑此问题!
