如何使用CSS在每个圆形div之间添加边界线？圆圈和边框线也必须有响应.我试图添加边框线,但它甚至没有显示..线必须居中在圆圈之间的中间.

height: 120px;
max-width: 120px;
text-align: center;
vertical-align: middle;
border: 5px solid #3A83C5;
border-radius: 50%;

<div …我试图返回带有简单文本的 PDF，但在下载文档时出现以下错误：无法加载 PDF 文档。任何有关如何解决此问题的想法表示赞赏。
MemoryStream ms = new MemoryStream();
PdfWriter writer = new PdfWriter(ms);
PdfDocument pdfDocument = new PdfDocument(writer);
Document document = new Document(pdfDocument);
document.Add(new Paragraph("Hello World"));
//document.Close();
//writer.Close();
ms.Position = 0;
string pdfName = $"IP-Report-{DateTime.Now.ToString("yyyyMMddHHmmssfff")}.pdf";
return File(ms, "application/pdf", pdfName);
