Description
**一款支持智能吸附的网页测量工具,让前端开发和 UI 设计更轻松。**
### ✨ 功能特性
- **智能吸附**:移动鼠标时按住 `Alt` (Mac 为 `Option`),可自动识别并吸附到页面元素,支持吸附到**边线、四个顶点和四条边线中点**,实时显示元素尺寸。吸附预览框颜色会自动与测量框区分,便于识别。
- **即时测量**:按住左键拖动,即可在吸附元素边缘的同时创建测量区域。
- **自由编辑**:双击已创建的测量区域进入编辑模式,可自由拖拽位置或调整大小。
- **Esc**:退出编辑模式
- **Backspace**:删除当前选中的测k区域
- **状态指示**:插件图标会根据启用状态变化(彩色=启用,灰色=关闭),方便识别当前状态。
- **快捷键帮助**:工具栏中的 `?` 按钮悬停可查看所有快捷键说明。
- **个性化定制**:
- **独立颜色和透明度**:每个测量框可单独设置颜色和透明度,选中元素时修改只影响当前选中项
- **全局模式**:开启后,修改颜色或透明度会同时影响所有已存在的测量框
- **单一模式**:开启后只能同时存在一个测量框,绘制新框时自动清除旧框
- **尺寸位置**:可配置尺寸信息显示位置(中心、四个角等)
- **虚线背景**:可选择测量框使用实心或虚线背景效果
- **参考线**:自动显示水平和垂直参考线,并标注 X、Y 坐标
- **十字线**:可配置是否鼠标十字参考线
- **快捷控制**:
- `f` 键(可配置):切换工具栏显示/隐藏
- `r` 键(可配置):切换参考线显示/隐藏
- `Shift` 键:切换尺寸数值显示/隐藏
- `Alt + z`(可自定义):全局快捷键启动/关闭插件
- 双击 `z` 键(可配置):页面内快速激活/关闭插件(需插件至少启动过一次)
- **本地支持**:在 `chrome://extensions` 中开启"允许访问文件网址",即可测量本地 HTML 文件。
- **兼容性**:支持移动端模拟模式(需将 `device type` 设置为 `no touch`)。

This is a really useful extension that works great. Why have permissions suddenly changed? Why do you need browser history?
