IE7 BUG: favicon. ICO is crazy! And seven suggestions for using favicon. ICO

In these years, we have always insisted on Personalization. If you have no personality, you would be embarrassed to say hello to people! Favicon. ICO is one of the products of personalized needs, but it is such a small "thing", but sometimes it takes us who are engaged in the Web to live for 555 ~~ I will never engage in Web in my next life ......
Let's talk about my crazy experiences.
According to the customer's requirements, the company logo should be made into icons that can be displayed in IE7 address bar, tabs, favorites. I thought this was a very small thing, but I did not expect it.
First, how to create an ico icon. Mainstream graph-making software does not seem to support this format, such as Photoshop and fireworks. As a result, when you find a large Tota icon to make software, it is shared software in, and you do not have to pay the money to save it, finally, I tried a usable one. Because ICO is multi-frame, a file contains a series of icon units of size and color depth. I will give it a big meal according to the ICO in windows, it consists of four dimensions: 48*48, 32*32, 24*24, and 16*16, and a total of 12 frames, including 32-bit, 24-bit, and 256-color.
Then, add Code <Link href = "http: // www. ***. COM/favicon. ICO "rel =" shortcut icon ">, Icon files and web pages are uploaded. Refresh the page and try again. Sorry, ie still gave me an" E "to restart IE, or "E", delete the cache, Disable IE, and re-open it, or "e", I am sweating. Run to Firefox and try it. the icon is displayed. Then, when the dog is grayed out, some people say that the favicon of IE must be a 16*16 ICo of 256 or 16 colors. Then, they re-create the icon and delete the frames of its half size, the ICO file is changed from 40 kb to 2 kb.
Upload again, refresh again ,........................ "E "............ My day! Close ie re-opening, or "e", delete the cache, Disable IE and re-open, or "e", I am sweating.
Now, is it ie, icons, or web pages?
When the webpage can display icons normally in Firefox, I am very skeptical about whether it is a problem with IE settings. I can see that there are several items in the favorites folder that have icons, however, there are also some websites with images that do not display icons. The chinamoocs bear's paw can display them, But Sina's eyes won't show them. What are the planes.
I checked the security options and add-ons of IE7 one by one, so there was nothing suspicious. Later, I thought about it. I finally found a seemingly relevant option "using personalized favorites". In my memory, this option is used to hide unused favorites, however, it may be related to the icon issue. enable it. After that, I deleted the cache and restarted ie. Sina's eyes could also come out, but my website was still "E "!
Then let's see if it's a problem with the icons I created?
I put Sina's eyes on my site, refresh, "E "! It seems that it is not an icon problem.
That is to say, the webpage is very suspicious!
Take a closer look at the webpage code. After comparing the codes of Netease And Sina, I guess it's because the mysterious doctype is playing a strange role?
So what is the doctype change? <! Doctype HTML public "-// W3C // dtd html 4.0 transitional // en" >,<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> ,......, I tried several of them but I still don't want to use them.
No constructive discoveries were found.
The ferry was disappointing.
I think, it is estimated that there are more ways for foreigners to search for English Yahoo! and English hoop dogs, search for IE7, favicon, And the dense e-text, in the end, we did not find a way to solve the problem, and we were still worried.
Looking at the code with a wide eye, I found a difference, that is, the link behind me is> rather than/>. Why? Add and try again, but it still does not display. I am on my day, I am on my day !!!

Why can't ie give face to any Firefox display?

Late at night, sleeping, no matter.
Wake up in the morning, the sun is high, the stomach is a little hungry, there is nothing to eat in the dormitory, there is no material food, you can only strengthen the spirit of food, that also say, boot online.
Open IE, what ?! I rubbed my eyes. That's right. The coveted icon is displayed on the Link bar! (To facilitate opening, add it to the link bar )...... So dizzy! Why did it not appear yesterday ?? Is it necessary to restart my computer after such a webpage change?

In fact, many people have asked questions on the Internet that the personalized favorites icon displayed in IE6 cannot be displayed after being upgraded to IE7.

Although the problem has been solved, I am still very annoyed! It's so hot!
After this lesson, we will summarize several points of favicon. ICO:
① Enable the IE7 advanced option "use personalized favorites.
② The icon must be a 16*16 ICO file of 256 or 16 colors.
③ <Link href = "http: // www. ***. COM/favicon. ICO "rel =" shortcut icon "/> you need to close it with a slash, whether or not you have used an unstrict doctype.
④ Ie needs to delete the cache.
⑤ Refresh. Add to favorites.
6. After the above five steps, you will be lucky. In most cases, the icon is not displayed, so let's take another step and restart IE.
7. If you are unlucky and cannot complete the above six steps, restart your computer.

After 7 steps, the icon is usually displayed.
What, if it is not displayed, then ........................ It is estimated that the rpwt is very serious!

I have gone through various crazy stages, such as sweat, perspiration, mad sweat, Afghanistan, and Genghis Khan. I hope everyone will be better at me!
