Sharing about html, css, javascript and other annotation methods

<!-- html注释:START -->

Content

is contained in “" of HTML comments.

Therefore, if the first line starts with "", JavaScript will ignore both lines, but not these two lines. The part between the lines. And if in JavaScript, the first line starts with "", then the program in between is included in a complete HTML comment, It will be ignored by browsers that do not support JavaScript and cannot be displayed.

In this way, the code can be hidden for browsers that cannot understand JavaScript, but there is no need to hide the code for browsers that can understand JavaScript.
