Analysis of getBoundingClientRect in various commonly used browsers_javascript skills
First go to the test code
<SCRIPT> <br>alert(document.getElementById("w3124").getBoundingClientRect().top ); <br></SCRIPT>
The following are the alert results
IE, FF, Chrome: 208
Maxthon of IE kernel: 215
TheWorld of IE kernel: 217
When the body is added with margin: 0; padding: 0, IE, FF, Chrome and Maxthon are all 200, but only TheWorld is 202
Then when the DOCTYPE statement in the header of the HTML code is removed, the values of FF, Chrome, and Maxthon are all 200, and because IE enters Quirks mode, the value at this time is 202, while TheWorld is still 202
Conclusion
FF, Chrome, and Maxthon always adhere to the Standards Mode (Standards Mode). IE also enters the Standards Mode (Standards Mode) after adding a statement. Only TheWorld always adheres to the Quirks Mode. It's evil!
Suggestion
For compatibility, add margin:0;padding:0 to the body, and pay attention to adding the DOCTYPE statement (with it, IE is quite obedient)
