Iframes, which stands for inline frames, are HTML tags. They allow web designers and developers to enrich the web page user experience while reducing duplication of content. Some tips for using iframes include setting attributes and scripting for attractive design, engaging interaction, and security.
With the iframe element, the developer instructs the parent web page to display another web page in a window. The developer can set attributes that control how the child page displays. Some of the attributes include setting a border, the child page height and width, security, and scrolling.
When using an iframe, appearance and functionality should be considered. The child page width and height should fit well within the design of the parent page, yet the appearance of the child page must be accounted for. For example, setting a border may highlight the child page, but sometimes having no border may improve the overall page appearance.
Scrollbars should also be appropriate for the child page. Eliminating scrollbars will give the page a clean look, but it may be frustrating for the user if he is not able to access content in the child page. When using an iframe, the developer should verify that all needed child page content displays before removing scrollbars.
Iframes are frequently used for banner ads. The advertising company can change the ad without needing the parent page to be modified. Using iframes in this scenario helps reduce duplication of content for the advertising firm and to reduce work for the organization that displays the ads.
Social media platforms may also allow developers to use iframes. The platform itself may grant only limited web development functionality. By using an iframe to access web pages that are hosted on a different server, the developer can take advantage of more functionality and provide a richer experience for the social media user.
Cross-browser compatibility can often be an issue with web page functionality, especially when using more sophisticated HTML elements. Most browsers support iframes, but the developer should check several popular browsers to ensure the child page displays correctly. He may find he needs to modify the code so the iframe displays attractively across browsers.
