    Alok Jain Agency Contractor

    UI Engineer & Consultant

    India - Portfolio: 23

    We ensures that our projects are tested on following criteria: - Pixel perfect layout, tested in all major browsers - HTML and CSS validation for W3C specifications - Page speed tested with YSlow and Google page speed - Accessibility rules and laws are followed - Google crawl test to ensure SEO compatibility. - Prints nicely on paper. We take HTML coding as an evolving science rather than an art. We have taken the road less travelled. Every single web page is meticulously planned for its code, and we ensured that it is far more satisfying to convert ONE PSD to HTML that is standard compliant, clean coded, and semantically correct web page, than to convert THREE normal PSDs to HTML.
