HTML (Hyper Text Markup Language) is the language behind the web pages of the Internet, created by Tim Berners-Lee, and uses a system of tags for applying layout, formatting and links to content. CSS (Cascading Style Sheets) are used to describe the presentation of the HTML. This section contains howtos, tips and tricks about how to use HTML and CSS.
CSS has a matching syntax for selectors which makes it possible to match the filename extension at the end of an href. This makes it easy to add an icon which relates to the link before or after the text part of the link.
Google recently released updated tracking code for Google Analytics which allows for asynchronous tracking. This means the analytics tracking can be done at the same time as rendering other content and therefore won’t delay other page content from rendering. This results in what appears to be faster rendering pages.
It is possible to specify custom user styles in Firefox. These override the default browser styles, and are in turn overridden by the website’s styles. User styles can be made to not be overridden by making them !important.
If an HTML table row contains only one <a> link it can be useful to make the entire row clickable and make it activate that link. This post shows how to make the entire row clickable with jQuery so that clicking anywhere in the row is the same as clicking that link.
It is so simple to clear floating HTML elements with overflow:auto but this doesn’t seem to be common knowledge. The most common way to clear floats is with a float clearing div, a hackish method involving writing content using the :after pseudo property, or unbelievably using <br clear="all"> as I saw posted on another site yesterday. This post looks at the simplicity of overflow:auto.
The CSS selectors :first-child and :last-child are used to apply styling to the first and last child elements of the parent. :first-child is part of the CSS 2.1 specification and :last-child CSS 3 so support is slightly limited for :first-child and more limited for :last-child.
