My friend Scott , who is paid to know these kinds of things, tells us:. The debate about whether a button or link should be used to download a file is a bit silly, as the whole purpose of a link has always been to download content. HTML is a file, and like all other files, it needs to be retrieved from a server and downloaded before it can be presented to a user. The difference between a Photoshop file, HTML, and other understood media files, is that a browser automatically displays the latter two. If one were to link to a Photoshop. They retrieve information and download it. They can get data, in regards to the functionality of form s, but it continues to be within the context of updating a web document, not downloading an individual file. Long story short, the download attribute is unique to anchor links for a reason.
download augments the inherent functionality of the link retrieving data. The user has to shift their mental model from flitting from page-to-page and filling out forms to navigating a file system and extracting compressed archives. For less technologically-savvy individuals, it can be a disorienting and frustrating context shift. As responsible designers and developers, we want to make the experience of interacting with a download link as good as it possibly can be. Anticipating and answering the following questions can help:. By itself, the verb Download would only signal what behavior will be triggered when the link is activated.
Do you know which one of those eight links gets you what you want? Remember that obvious always wins. While it is possible to make your compliance checks happy by using a visually hidden CSS class to hide the noun portion of your download, it places extra cognitive burden on your users. KB, MB, GB, TB. Know your audience. A file with a size of KB will download much faster than a file with a size of 2 GB , yet its number is drastically larger. For larger files, the wait time can be especially problematic.
A standard download is an all-or-nothing affair—interruptions can corrupt them and render them useless. Worse, it can waste valuable data on a metered data plan, an unfortunately all-too-relevant concern. There is hidden nuance living in the gap between reported and actual connection. See the Pen Download movie by Eric Bailey ericwbailey on CodePen. Your user is going to know the particulars of their connection quality better than you ever will. Now they have what they need to make an informed decision, with a little intentional ambiguity to temper expectations. Progress bars are UI elements that show how close a computational task is to completion.
Browsers already supply UI to indicate how the download is progressing. Adding them introduces unnecessary implementation and maintenance complications—especially when combined with the issues in determining connection speed and quality outlined earlier. Sell the user on why they should care. Will it remove frustration by fixing an existing problem? Will it increase enjoyment by adding a new feature? Will it reassure by making things more secure? If I am downloading router firmware, I may not understand or care about the nitty-gritty of what the update does behind the scenes. However, some high-level communication about why I need to undertake the endeavor will go a long way.
See the Pen Describe what the download does by Eric Bailey ericwbailey on CodePen. Instructions on what to do after the download has completed could be useful. Again, knowing your audience is key. With our router example, it is entirely possible that less technically-savvy individuals will find themselves on the product support page. After a download has been initiated, step-by-step information on how to install the new firmware, as well as links to relevant support resources could go a long way to alleviating negative feelings. This is practical empathy. These savings means organizational resources can be reallocated to other important endeavors. Links use underlines. A good practice from both a user experience and an accessibility perspective is to create a distinction between internal and external links. This means creating an indicator that a link does something other than take you to another place on your website or webapp.
For links that go off-site, a common practice is to use an arrow breaking out of a box. For downloads, a downward-facing arrow is the de facto standard. Some may feel that the presence of the download attribute is redundant when applied to links the browser already knows to store. I disagree. In addition to being an unambiguous semantic marker in the HTML, the download attribute can serve as a simple and elegant styling hook. CSS attribute selectors —code that lets us create styling based on the qualities that help describe HTML elements—allow us to target any link that is a download and style it without having to attach a special class:. Combined with the text describing the download, the presence of the icon clearly communicates that when you activate this link, download behavior will follow.
It also provides extra target area, great for touch devices. Targeting both the presence of the download attribute and the file extension at the end of the string in the href attribute allows us to get even fancier. We can take advantage of the cascade to set up a consistent treatment for all icons, but change the icon itself on a per-filetype basis. This is great for situations where there are multiple kinds of things you can download on a single page:. See the Pen Download icons by Eric Bailey ericwbailey on CodePen. Remember to only include the selectors you need, so as to not create unnecessary bloat in your production CSS. It will improve performance—just remember to make it accessible! The download attribute can accept an optional value, allowing the author to create a custom, human-friendly name for the downloaded file.
For complicated sites, this attribute allows us to create downloads that make sense to the person requesting them, while also taking advantage of features like CDNs and dynamically-generated files. Not a lot of complicated backend sorcery here, just a little template logic:. Keeping content looking and behaving like the HTML elements used to describe it is great for reinforcing external consistency. Externally consistent content is great for ensuring people can, and will use your website or webapp. Use is great for engagement, a metric that makes business-types happy. And yet, link-y buttons and button-y links are everywhere. We can lay blame for this semantic drift squarely at the feet of trend. Designers and developers eager to try the latest and greatest invite ambiguity in with outstretched arms. Leadership chases perceived value to stay relevant. Websites can be both beautiful and accessible. Take a little time to review the fundamentals—you just might discover something simple that helps everyone get what they need with just a little bit less fuss.

DigitalOcean joining forces with CSS-Tricks! Need a heading? Want a paragraph? Want a download? What best describes a download? There seems to be a lot of confusion over when to use buttons and when to use links. Much like tabs versus spaces or pullover hoodies versus zip-ups, this debate might rage without end. However, the W3C provides us with an important clue as to who is right: the download attribute. They form the Semantic Web , the terribly wonderful, wonderfully terrible tangled ball of information that enables you to read this article at this very moment.
Anchor link elements also possess a number of unique attributes that help control how they connect to other documents and files. One of those attributes is called download. It tells the browser that the destination of the link should be saved to your device instead of visiting it. Any kind of file can be a download! This even includes HTML, something the browser would typically display. The presence of the attribute is effectively a human-authored flag that tells the browser to skip trying to render something it has retrieved and just store it instead:. JavaScript is more brittle than we care to admit. Using anchors for your download means that a person can access what they need, even in suboptimal situations. A robust solution is always the most desirable—in a time of crisis, it might even save a life.
This might sound hyperbolic, but having a stable copy of something that works offline could make all the difference in a time of need.

Firefox decided that since it could render the image, it would display it rather than download it. Basically, some browsers will ignore the download attribute if the document type is one that it can render natively. Even if the downloaded file is a HTML file which Firefox can render natively it triggers the download. Note that Chrome is going to follow the same behavior as Firefox.
