Web design is the procedure for creating internet sites . It encompasses many diverse factors, including page layout, content production, and image design. As the provisions
web design and web development are frequently used interchangeably, web design is a subset of the broader group of web development.

Sites are created with a mark up language known as HTML. Web designers build webpages using HTML tags which define the material and meta-data of each web page. The design and appearance of those weather within a webpage are usually defined using CSS, or cascading style sheets. Therefore, most websites include a combination of HTML and CSS that defines how each page can look in a browser.

Some web designers prefer to hand code pages (scanning HTML and CSS from scratch), while others use a"WYSIWYG" editor like Adobe Dreamweaver. Such a editor gives a visual interface for designing the webpage layout and the program automatically produces the corresponding HTML and CSS code. Still another popular means to design web sites is with an content management system such as WordPress or even Joomla. These services offer different website templates that may be used as a startingpoint for a fresh website. Web-masters can subsequently add material and customize the design working with an internet interface.

While HTML and CSS are utilised to design the appearance and feel of a site, images needs to be generated separately. Consequently, graphic design may overlap with web design, since graphic designers often create images for use on the internet. Some graphics apps like Adobe Photoshop even incorporate a"Save for Web…" option that provides a simple means to export images in a format optimized to web publishing.
