David Hyatt, lead developer for Apple's Safari web browser talks about how Safari and Mozilla renders web pages, and the algorithms it uses to render partially downloaded data. Interesting if you are a HTML jock.
A few tips I gleaned:
- Only use one CSS file and make sure that the link to it is at the
top of the web page. This is because all CSS has to be loaded before
any rendering can properly occur. The browser might attempt to draw
something before all the CSS arrives, but an unsightly white flash will
occur as a redraw will have to be made as soon as the rest of the CSS
- Adding a defer attribute in the script tag like this
function can dynamically generate HTML, and the defer attribute
deferring it, after HTML rendering.
It also shows that a properly implemented browser rendering pipeline will significantly benefit from multi-core processors and hyperthreading. Does anyone know whether these browsers take advantage of this? [PHP Everywhere – Thoughts on PHP and other programming technologies by John Lim]>
