Valid CSS and XHTML – Compliant with Web Standard
I always try to make the theme compliant with web standard. You will see icons at right bottom of the theme. What is compliant with web standard mean? It means that the theme has been checked with Validation Service and it got valid CSS and XHTML. When you see Valid CSS and Valid XHTML icons, it shows that the theme is checked and no errors found in CSS and XHTML.
CSS Validation Service
You can check Cascading Style Sheets for free whether by URI, File Upload or Direct Input at W3C CSS Validation Service.
Markup Validation Service
You can check the markup (HTML, XHTML etc.) of Web documents by URI, File Upload or Direct Input at W3C Markup Validation Service.
When you have the Valid CSS and XHTML icons on your weblog, it will show to your readers that you have taken the care to create an interoperable web page. As professional designer, compliant with web standard is important.
