Tools and technologies
Web designers use a variety of different tools depending on what part of the production process they are involved in. These tools are updated over time by newer standards and software but the principles behind them remain the same. Web designers use both vector and raster graphics editors to create web-formatted imagery or design prototypes. Technologies used to create websites include W3C standards like HTML and CSS, which can be hand-coded or generated by WYSIWYG editing software. Other tools web designers might use include mark up validators and other testing tools for usability and accessibility to ensure their websites meet web accessibility guidelines.
User experience design and interactive design
User understanding of the content of a website often depends on user understanding of how the website works. This is part of the user experience design. User experience is related to layout, clear instructions and labeling on a website. How well a user understands how they can interact on a site may also depend on the interactive design of the site. If a user perceives the usefulness of the website, they are more likely to continue using it. Users who are skilled and well versed with website use may find a more distinctive, yet less intuitive or less user-friendly website interface useful nonetheless. However, users with less experience are less likely to see the advantages or usefulness of a less intuitive website interface. This drives the trend for a more universal user experience and ease of access to accommodate as many users as possible regardless of user skill. Much of the user experience design and interactive design are considered in the user interface design.
Advanced interactive functions may require plug-ins if not advanced coding language skills. Choosing whether or not to use interactivity that requires plug-ins is a critical decision in user experience design. If the plug-in doesn’t come pre-installed with most browsers, there’s a risk that the user will have neither the know how or the patience to install a plug-in just to access the content. If the function requires advanced coding language skills, it may be too costly in either time or money to code compared to the amount of enhancement the function will add to the user experience. There’s also a risk that advanced interactivity may be incompatible with older browsers or hardware configurations. Publishing a function that doesn’t work reliably is potentially worse for the user experience than making no attempt. It depends on the target audience if it’s likely to be needed or worth any risks.
Part of the user interface design is affected by the quality of the page layout. For example, a designer may consider whether the site’s page layout should remain consistent on different pages when designing the layout. Page pixel width may also be considered vital for aligning objects in the layout design. The most popular fixed-width websites generally have the same set width to match the current most popular browser window, at the current most popular screen resolution, on the current most popular monitor size. Most pages are also center-aligned for concerns of aesthetics on larger screens.
Fluid layouts increased in popularity around 2000 as an alternative to HTML-table-based layouts and grid-based design in both page layout design principle and in coding technique, but were very slow to be adopted.[note 1] This was due to considerations of screen reading devices and varying windows sizes which designers have no control over. Accordingly, a design may be broken down into units (sidebars, content blocks, embedded advertising areas, navigation areas) that are sent to the browser and which will be fitted into the display window by the browser, as best it can. As the browser does recognize the details of the reader’s screen (window size, font size relative to window etc.) the browser can make user-specific layout adjustments to fluid layouts, but not fixed-width layouts. Although such a display may often change the relative position of major content units, sidebars may be displaced below body text rather than to the side of it. This is a more flexible display than a hard-coded grid-based layout that doesn’t fit the device window. In particular, the relative position of content blocks may change while leaving the content within the block unaffected. This also minimizes the user’s need to horizontally scroll the page.
Responsive Web Design is a newer approach, based on CSS3, and a deeper level of per-device specification within the page’s style sheet through an enhanced use of the CSS @media rule. In March 2018 Google announced they would be rolling out mobile-first indexing.Sites using responsive design are well placed to ensure they meet this new approach.
Main article: typography
Web designers may choose to limit the variety of website typefaces to only a few which are of a similar style, instead of using a wide range of typefaces or type styles. Most browsers recognize a specific number of safe fonts, which designers mainly use in order to avoid complications.
Font downloading was later included in the CSS3 fonts module and has since been implemented in Safari 3.1, Opera 10 and Mozilla Firefox 3.5. This has subsequently increased interest in web typography, as well as the usage of font downloading.
Most site layouts incorporate negative space to break the text up into paragraphs and also avoid center-aligned text.
The page layout and user interface may also be affected by the use of motion graphics. The choice of whether or not to use motion graphics may depend on the target market for the website. Motion graphics may be expected or at least better received with an entertainment-oriented website. However, a website target audience with a more serious or formal interest (such as business, community, or government) might find animations unnecessary and distracting if only for entertainment or decoration purposes. This doesn’t mean that more serious content couldn’t be enhanced with animated or video presentations that is relevant to the content. In either case, motion graphic design may make the difference between more effective visuals or distracting visuals.
Motion graphics that are not initiated by the site visitor can produce accessibility issues. The World Wide Web consortium accessibility standards require that site visitors be able to disable the animations.
Main article: Static web page
A static website stores a unique file for every page of a static website. Each time that page is requested, the same content is returned. This content is created once, during the design of the website. It is usually manually authored, although some sites use an automated creation process, similar to a dynamic website, whose results are stored long-term as completed pages. These automatically-created static sites became more popular around 2015, with generators such as Jekyll and Adobe Muse.
The benefits of a static website are that they were simpler to host, as their server only needed to serve static content, not execute server-side scripts. This required less server administration and had less chance of exposing security holes. They could also serve pages more quickly, on low-cost server hardware. These advantage became less important as cheap web hosting expanded to also offer dynamic features, and virtual servers offered high performance for short intervals at low cost.
Almost all websites have some static content, as supporting assets such as images and style sheets are usually static, even on a website with highly dynamic pages.
Main article: Dynamic web page
Dynamic websites are generated on the fly and use server-side technology to generate webpages. They typically extract their content from one or more back-end databases: some are database queries across a relational database to query a catalogue or to summarise numeric information, others may use a document database such as MongoDB or NoSQL to store larger units of content, such as blog posts or wiki articles.
In the design process, dynamic pages are often mocked-up or wireframed using static pages. The skillset needed to develop dynamic web pages is much broader than for a static pages, involving server-side and database coding as well as client-side interface design. Even medium-sized dynamic projects are thus almost always a team effort.
When dynamic web pages first developed, they were typically coded directly in languages such as Perl, PHP or ASP. Some of these, notably PHP and ASP, used a ‘template’ approach where a server-side page resembled the structure of the completed client-side page and data was inserted into places defined by ‘tags’. This was a quicker means of development than coding in a purely procedural coding language such as Perl.
Both of these approaches have now been supplanted for many websites by higher-level application-focused tools such as content management systems. These build on top of general purpose coding platforms and assume that a website exists to offer content according to one of several well recognised models, such as a time-sequenced blog, a thematic magazine or news site, a wiki or a user forum. These tools make the implementation of such a site very easy, and a purely organisational and design-based task, without requiring any coding.
Editing the content itself (as well as the template page) can be done both by means of the site itself, and with the use of third-party software. The ability to edit all pages is provided only to a specific category of users (for example, administrators, or registered users). In some cases, anonymous users are allowed to edit certain web content, which is less frequent (for example, on forums – adding messages). An example of a site with an anonymous change is Wikipedia.
