Title attribute with value more than 512 character gets lost

Is there any way this count(512) could be increased?

No. This will have been set when IE's code was written. The IE developers will have chosen 512 characters as a sensible maximum for the title attribute.

The fact that you need to store more than 512 characters in it is a code smell and you should be looking at storing that data in a different way, or you need to shorten the string yourself to keep only the data you need.

Stackoverflow, for example, only shows some of a post when hovering over it on the homepage, not the whole post. The tooltip would be too large for one, and some browsers hide the tooltip after a short amount of time making reading up to 512 characters let alone more very difficult.

Website title element max character length

Optimal title length. Google typically displays the first 50–60 characters of a title tag. If you keep your titles under 60 characters, it will display your Title Properly and i hope this answer help you..

Is there any character length limitation for HTML5 title tooltip in IE9 and chrome

Amit,

Few points,

1. I am not sure if IE9 supports HTML5 (refer WikiPedia
2. I am not sure if Title attribute is different in HTML5 and HTML4.01
3. In HTML 4.01, the title attribute length in IE is restricted to 512
   (refer
   http://msdn.microsoft.com/en-US/library/ie/ms534683(v=vs.85))

Hope that helps and sorry if I have misunderstood your question :-)

Is there a limit to the length of HTML attributes?

HTML5 has no limits on the length of attribute values.

As the spec says, "This version of HTML thus returns to a non-SGML basis."

Later on, when describing how to parse HTML5, the following passage appears (emphasis added):

The algorithm described below places
no limit on the depth of the DOM tree
generated, or on the length of tag
names, attribute names, attribute
values, text nodes, etc. While
implementors are encouraged to avoid
arbitrary limits, it is recognized
that practical concerns will likely
force user agents to impose nesting
depth constraints.

Therefore, (theoretically) there is no limit to the length/size of HTML5 attributes.

How to increase default hover duration of a title attribute (tooltip)

I think this is operating system dependent and you should not try to override that.

The best way will be to create a custom tooltip.
