Css 在textarea引导4旁边显示图像

我需要使用Bootstrap4在文本区域旁边显示一个图像。但我有一个显示问题：

我想要的是它看起来像的图像和文本区域：

无论是在pc上还是在响应模式下，图像都始终与前一幅图像相同

这是我的实际HTML组件的代码：

<div class="container">
<div class="row">
          <div class="col-lg-12">
            <div class="col-lg-4">
                <img 
                data-src="holder.js/200x200" 
                class="rounded float-left" 
                alt="100x100" 
                src="data:image/svg+xml;charset=UTF-8,%3Csvg%20width%3D%22200%22%20height%3D%22200%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20200%20200%22%20preserveAspectRatio%3D%22none%22%3E%3Cdefs%3E%3Cstyle%20type%3D%22text%2Fcss%22%3E%23holder_164e3f66702%20text%20%7B%20fill%3Argba(255%2C255%2C255%2C.75)%3Bfont-weight%3Anormal%3Bfont-family%3AHelvetica%2C%20monospace%3Bfont-size%3A10pt%20%7D%20%3C%2Fstyle%3E%3C%2Fdefs%3E%3Cg%20id%3D%22holder_164e3f66702%22%3E%3Crect%20width%3D%22200%22%20height%3D%22200%22%20fill%3D%22%23777%22%3E%3C%2Frect%3E%3Cg%3E%3Ctext%20x%3D%2274.4296875%22%20y%3D%22104.5%22%3E200x200%3C%2Ftext%3E%3C%2Fg%3E%3C%2Fg%3E%3C%2Fsvg%3E"

我尝试了几种方法来更改css以获得此效果，但我做不到

多谢各位

只需将col-lg-12 div全部拆下
