![]() ![]() Printing is another consideration that a reader correctly points out. In contrast, plain text is inherently accessible (though it can definitely be too complicated for disabled users to understand, but that’s a standard writing issue which you should consider in any case.) Pages and widgets must be coded with accessibility in mind, which is an added development effort. Accessibility is an important consideration.When content is hidden, people might ignore information. Headings and titles must be descriptive and enticing enough to motivate people to “spend” clicks on them. An extra step is required to see the information. Hiding content behind navigation diminishes people’s awareness of it.Acquiring click targets, such as links and buttons, and waiting for content to appear requires work and wastes precious time that users don’t want to give. However, resentment ensues when a click is considered a wasted effort it doesn’t take many wasted clicks to escalate people’s reaction to full-blown defiance. ![]() Readers treat clicks like currency: they don’t mind spending it if the click is worthwhile and has value. (Every single decision, no matter how minor or how easy, adds cognitive load.) The experience feels less fragmented with fewer attention switches. It is easier to scroll down the page than to decide which heading to click on. In this situation, it’s better to expose all the content at once. If people need to open the majority of subtopics to have their questions answered or to get the full story then an accordion is not the way to go. Forcing people to click on headings one at a time to display full content can be cumbersome, especially if there are many topics on the list that individuals care about.While accordions sound ideal for presenting complex content, like with many other widgets and implementations, they are not a one-size-fits-all solution. Without proper cues people are confused about where they are on the site. People expect clicking a link will load a new page. Accordions can be a better alternative to within-page links, which are problematic because they break people’s mental model for hypertext links.Hiding (some of) the content can make the web page appear less daunting.This allows users to form a mental model of the information available. The headings serve as a mini-IA of the page.Collapsing the page minimizes scrolling.There are other advantages to applying accordions to long, content-rich pages: By allowing people to control what content they see and what remains hidden, the information feels less overwhelming. In theory, it is a useful way to present content. In theory, this concept sounds reasonably human centered. Giving people control is #3 on the list of the top heuristics for usable design. Allowing people to have control over the content by expanding it or deferring it for later lets them decide what to read and what to ignore. It is one of many ways you can expose content to users in a progressive manner. These names are a reference to the type of accordion patented by Cyrill Demian, which concerned "automatically coupled chords on the bass side".An accordion menu is a vertically stacked list of headers that can be clicked to reveal or hide content associated with them. Today, native versions of the name accordion are more common. The oldest name for this group of instruments is actually harmonika, from the Greek harmonikos, meaning harmonic, musical. Additionally, the accordion is sometimes used in both solo and orchestra performances of classical music. Some popular music acts also make use of the instrument. In Europe and North-America, it is often associated with busking. The accordion -which is mainly manufactured in Italy -is often used in folk music in Europe, North America and South America, and in some countries, such as Brazil, Colombia and Mexico, it is also commonly used in mainstream pop music. The performer normally plays the melody on buttons or keys on the right-hand manual, and the accompaniment, consisting of bass and pre-set chord buttons, on the left-hand manual. ![]() The instrument is played by compressing or expanding the bellows while pressing buttons or keys, causing valves, called pallets, to open, which allow air to flow across strips of brass or steel, called reeds, that vibrate to produce sound inside the body. A person who plays the accordion is called an accordionist.
