图片加字，用我最爽

news 2026/6/23 2:17:13

添加后的文字可用鼠标拖拽——没这个就成了最不爽了。

HTML+JavaScript:

<html><head><meta charset="UTF-8">
<title>图片加字，用我最爽</title>
<style>
body {display: flex; /* 设置为弹性布局容器 */justify-content: center; /* 主轴（默认水平）居中 */align-items: center; /* 交叉轴（默认竖直）居中 */
}
* { font: 12pt sans-serif; }
img { pointer-events: none; user-select: none; }
button { width: 6em; padding: 8px; font-size: 13pt; }
#file { display: none; }
textarea { line-height: 150%; }
/* p和div都是独占一行的块元素。p的margin-top/bottom默认不为0 */
.draggable {position: absolute; margin: 0; padding: 0;user-select: none; cursor: move;
}
.draggable:active { cursor: none; }
</style></head><body>
<!--在未设置CSS定位和z-index属性的默认情况下，后出现在源码中的元素覆盖先出现的元素-->
