Hi!
1. place the css in the header or different file?
2. Host the images on cdn or on my server?
3. if I point to a jquery file in my header that weights 100kb, is that suicide for lander loading times?
4. the jquery roller (you can see a basic review here http://www.lukepeerfly.com/jquery-mobile-themeroller ). Is it good or bad idea in terms of lander loading times?
Woohoo ,thanks!
1. CSS in the head with style tags.
2. ALL static content on a CDN.
3. Yes. Unless you use a CDN-hosted one that 99% of people will have cached. Use Google's repository.
4. Test it. You don't know what load times your going to get or how this will influence LP profitability. Test it.
mm thanks man, I'll point to google's jquery. for example, the link to version 1.4.3 is this one? am I correct?
//ajax.googleapis.com/ajax/libs/jquerymobile/1.4.3/jquery.mobile.min.css
and 2) if I have big image thats hidden at first on my lander, will it slow the initial loading time?
3) how to reduce gif animation size without lossing the animation?
1) Yes that is correct - that is the Google hosted library. Do note that using the protocol relative (//) URL means your page won't load the library if you are loading the page from your computer (so have as http:// and change to // when it goes live on your server).
2) You mean an image that's hidden by CSS? Of course. It has to get downloaded, whether the browser displays it to the user or not is irrelevant.
3) You just need to tweak settings in whatever program you save the GIF from. Do it as you save it. Don't try to optimise it afterward - make it sensible first time around.
