How to flash html

HTML is the most basic web development language and can implement simple web elements such as headers, paragraphs, tables, lists, links, etc. But if you want to add more interactive and dynamic content to your web pages, you will need more powerful tools, such as Flash. Many web designers like to embed Flash animations in HTML pages to make their pages more vivid and eye-catching. This article will explore how to embed Flash into HTML pages, as well as some common mistakes and solutions.

Step One: Create Flash Animation

Before embedding Flash into an HTML page, you need to create a Flash animation. There are many Flash writing software options available, including Adobe Animate and OpenFL. However, in many cases, developers may obtain FLA files from professional designers and need to convert these files to SWF format in order to embed them into HTML pages.

Step 2: Add Flash to the HTML page

To add Flash to the HTML page, you must use the embedded tag (embed tag). Here is a basic embed tag example:

The src attribute points to the URL of the Flash file , width and height attributes define the size of Flash animation. In addition, other properties can be used to adjust the actual appearance and behavior. For example:

This code snippet will set the background color to white, close the Flash menu, and make the animation loop.

Step 3: Support older browsers

Due to the advancement of HTML5 technology, almost all modern browsers support HTML5 media elements. However, in the past, browsers might not have any built-in Flash player or Flash-enabled plug-in. In this case, you need to use object tags or dynamic impression tags to be compatible with older browsers and other devices (such as mobile devices).

The following is an example of an object tag:

<param name="movie" value="flashfile.swf">
<!--[if !IE]>-->
<object type="application/x-shockwave-flash" data="movie.swf" width="320" height="240">
    <param name="movie" value="flashfile.swf">
<!--<![endif]-->
<!--[if IE]>
    <param name="movie" value="flashfile.swf">
<![endif]-->

This object tag uses two nested object tags. The first object tag specifies the classid attribute, which is the standard identifier used by browsers to identify and load Flash files. The first object tag also defines a param element that points to the URL of the Flash file. The first object tag was designed for older versions of IE (i.e. IE5.5 and older).

The second object tag loads Flash in all other browsers. It specifies the Flash file type using the type attribute "application/x-shockwave-flash" and points to the URL of the Flash file. Here, the second object tag creates an alternate embed tag and specifies the same URL to the Flash file as when it's not using IE.

If you need to support mobile devices, it is recommended to use HTML5 video and audio elements instead of Flash.

Step 4: Deal with common problems

When embedding Flash, you often encounter problems. Here are some of the most common problems, and their solutions:

1. Flash fails to load: If Flash fails to load and the src or data attribute of the embedded tag or object tag points to the correct URL and path, There may be a problem with the Flash file itself. You may need to recreate the Flash file using a different Flash authoring tool, or use a tool like Swiffy to convert Flash to HTML5.
2. File size of the Flash file: If the Flash file is too large, it will take some time to load, which may affect the load time of the web page. Optimize Flash files and reduce their file size to help with faster loading times.
3. Transparency issues: If the Flash package is taller than other elements at the bottom of the HTML page, then you may need to use the wmode attribute in the embed tag to resolve transparency issues. For example:

4. Cannot be used in Firefox Load Flash in Firefox: If Flash doesn't work properly in Firefox, you may need to install a Flash plug-in. The built-in Firefox plug-in may not work in all situations, and the appropriate version of the Flash plug-in may need to be manually downloaded and installed.

Summary

Embedding Flash animations into HTML pages can make your web pages more dynamic and attractive. This task is very easy to accomplish using embed tags or object tags, but you may run into some common problems. By following the steps and solutions in this article, you can successfully embed Flash animations in HTML pages.
