Hi, When you are drawing some text, you create a RenderText(RenderObject) which has all the rendering info & the m_style of RenderText has the style info required to render the text.
Let's consider the following style data I have in my html page <style type="text/css"> body.rahaman{ font:30px courier; } </style> <body class="rahaman"> Rahaman </body> Once the HTMLTreeBuilder parses the token, it creates HTMLStyleElement & CSSStyleSheet & then asks the CSSParser to parse the StyleSheet. From there it comes to CSSParser::parseValue()=>CSSParser::parseFont() as the I have only used font property We create a FontValue (which contain all the attribute a font property can have like style, size, variant, family etc=> in this font_family, you can actually see the font name you have used ). In CSSParser::parseFont, we populate the FontValue structure (you can find the font family name in font->family), calls CSSParser::addProperty() where we create a CSSProperty with the FontValue/CSSValue being passed & this property is being stored in CSSParser::m_parsedProperties. Then we call CSSParser::createStyleRule where we used the m_parsedProperties mentioned before to create a CSSMutableStyleDeclaration & set this declaration for the CSSRule. We then create CSSStyleSelector and call CSSStyleSelector::styleForElement for the root element. Here somehow (I don't have much details what happens in berween but figured out that we retrieve the same CSSMutableStyleDeclaration mentioned above) & call CSSStyleSelector::applyProperty(). Here each StyleSelector has its RenderStyle (m_style), where from we retrieve the FontDescription & add the properties accordingly. On the other hand, each RenderObject (the corresponding node in the RenderTree for a node in DOM tree) has RenderStyle, which gets the value we retrieved above. Finally we call GraphicsContext::drawText() passing the Font which we have retrieved from the RenderStyle we dsicussed above. I am not sure if this is what you were looking for, I just shared whatever I knew of the related area. Please let me know if you need anything else.
