Khi tạo một bài viết với blockquote , văn bản trích dẫn đó sẽ được thụt vào bên trong và làm cho nó nổi bật. Tuy nhiên,style mặc đinh của blogspot rất đơn điệu, nếu bạn muốn thay đổi nó thì bạn có thể chỉnh sửa nó bằng lệnh blockquote{ lệnh css }. 
Blockquotes là cách để làm nổi bật ý tưởng chính của bạn giữa các nội dung khác Thủ thuật được phát triển bởi 24wworks.

Các bạn có thể xem Demo TẠI ĐÂY (Trong TemPlate của mình mình để hình trắng do vậy các bạn không thấy có thẻ ở đầu dòng) các bạn có thể nhìn hình để thấy rõ hơn
☼ Bây giờ ta bắt đầu thủ thuật :
1. Đăng nhập blog
2. Vào bố cục (layout)
3. Vào chỉnh sửa code HTML (edit code HMTL).
Ctrl + F : tìm bỏ các đoạn : 

blockquote {......}
.post blockquote {....}
.post blockquote p {.....}
Tại vì mỗi template có một mẫu blockqoute khác nhau. Nên các bạn tìm đoạn code tương tự mà xóa nhé. Nhưng đừng bỏ cái blockquote trong phần reset css nhé :D 


- Sau khi xóa bỏ xong,bạn thêm đoạn code sau vào ngay chỗ blockquote xóa đó. Hoặc thêm ở  trước thẻ ]]></b:skin> 
- Bạn nên sử dụng firefox để test mã blockqoute nào hợp với template của bạn trước rồi hãy quyết định mang vào template. 
Chúc bạn hài lòng.
