How to structure the framework in the production of scientific research websites

As we all know, the most common use of frameworks is navigation. A group of frames usually includes a frame with a navigation bar and another frame that displays the main content page. However, the design of the framework can be complex; In many cases, you can create pages without frames, which can achieve many of the same effects as using a set of frames. For example, if you want the navigation bar to appear on the left side of the page, you can replace your page with a set of frames, or only include the navigation bar on each page of the site.

Many professional web designers don't like to use frames, and many people who surf the Internet don't like them either Scientific research website production Frame. In most cases, this aversion is caused by websites that encounter inefficiency or unnecessary use of frames (for example, the frameset of navigation frame content will be reloaded every time visitors click the navigation button). If used properly, frameworks are very useful for some sites (for example, keep the navigation controls in one framework unchanged while allowing the content of other frameworks to change).

Not all browsers provide good framework support. Frames may be difficult to display for visitors who cannot navigate. Therefore, if you really want to use frameworks, you should always provide the noframes section in the frameset to facilitate visitors who cannot view these frameworks. You'd better also provide a clear link to the frameless version of the website for visitors who do not like to use the framework, although their browser supports the framework.

This framework has the following advantages:

Visitors' browsers do not need to reload navigation related graphics for each page; Each frame has its own scroll bar (if the content is too large to be displayed in the window), so visitors can scroll these frames independently; For example, when the content page in the frame is long, if the navigation bar is located in different frames, visitors who scroll down to the bottom of the page can use the navigation bar without scrolling back to the top.

The use of the framework has the following disadvantages:

It may be difficult to achieve accurate graphic alignment of elements in different frames; Testing navigation can be time-consuming; The URL of each frame page will not be displayed in the browser, so it may be difficult for visitors to mark a specific page as a bookmark (unless you provide server code so that visitors can load the frame version of a specific page.
