The fold is a term carried over from newspaper design and pagination (where the fold referred to the physical fold in the paper). The fold in a website is the point on the webpage that rests at the bottom of someone’s browser (in other words, to see anything below the fold, they would have to scroll down). There are varying opinions on how important the fold is in web design.
Favicons are tiny (generally 16×16 pixels, though some are 32×32 pixels), customizable icons displayed in the web address bar in most browsers next to the web address. They’re either 8-bit or 24-bit in color depth and are saved in either .ico, .gif or .png file formats.
The front-end is basically the opposite of the back-end. It’s all the components of a website that a visitor to the site can see (pages, images, content, etc.) Specifically, it’s the interface that visitors use to access the site’s content. It’s also sometimes referred to as the User Interface.
Fixed Width Layout
A fixed width layout has a set width (generally defined in pixels) set by the designer. The width stays the same regardless of screen resolution, monitor size, or browser window size. It allows for minute adjustments to be made to a design that will stay consistent across browsers. Designers have more control over exactly how a site will appear across platforms with this type of layout.
The focal point of a web site is the spot on a web page that they eye is naturally drawn to. This could be an image, a banner, text, Flash content, or just about anything else. You want to make sure that whatever is acting as your focal point is the most important part of your site.
Font family is a group designation for defining the typefaces used in CSS documents. The font family tag generally lists multiple fonts to be used, and usually ends with the generic font category (such as “serif” or “sans-serif’).
The font weight refers to how thick or thin (bold or light) a font looks.
