The reason for using less iframes is that iframes will introduce additional complexity, affect the performance of the web page, pose security risks, and have poor compatibility on mobile devices. Detailed introduction: 1. iframe will introduce additional complexity. When a web page contains multiple nested iframes, the page structure will become very complex, which will increase the difficulty of development and maintenance, especially when the page layout needs to be modified. Or when adding new features, since each iframe is an independent document, cross-iframe communication becomes complicated, etc.

As a programmer, I am often faced with the need to choose what technology to use to implement a project. When developing front-end interfaces, I usually avoid using iframes. Here are a few reasons why I think they should be used less often.

First, iframes introduce additional complexity. When a web page contains multiple nested iframes, the page structure becomes very complex. This makes development and maintenance more difficult, especially when the page layout needs to be modified or new functionality added. At the same time, since each iframe is an independent document, cross-iframe communication becomes complicated. Therefore, using iframes may increase project complexity and maintenance costs.

Secondly, iframe will affect the performance of the web page. Each iframe needs to load independent HTML documents and resources, which increases page loading time and bandwidth consumption. If a web page contains multiple iframes, the overall loading time will increase significantly. In addition, because the iframe is separated from the main page, the browser cannot effectively cache and optimize their resources. This may result in slower page response and reduced user experience.

Third, iframe has security risks. Since iframes allow one web page to be embedded within another web page, this can be exploited maliciously. Attackers can embed malicious code into iframes to steal users' sensitive information or perform other malicious behaviors. Although modern browsers have taken some security measures to limit script execution in iframes, there are still some security risks. Therefore, to keep users safe, I generally avoid using iframes.

Finally, iframes are less compatible on mobile devices. Due to the limited screen space of mobile devices, embedding a web page within another web page may cause the page to display incorrectly. In addition, due to the limited network environment and performance of mobile devices, loading multiple nested iframes may cause the page to load slowly or freeze. Therefore, using iframes on mobile devices may impact user experience.

To sum up, although iframe has some special application scenarios, in most cases, I will try to avoid using iframe. By using other alternatives such as Ajax, loading content dynamically or using a modern front-end framework, the needs of the project can be better met and provide better performance and security. As a programmer, I will weigh the pros and cons based on the specific situation and choose the most appropriate technical solution to achieve the project goals.
