How do media queries work




















The various uses of your content are also important. Notice that in the image above, the standard web view on the left renders some elements completely unusable when viewed on a smaller device. Such behavior will also increase the chances that your user makes an error, slowing down their experience. In practice, this can manifest itself as decreased page views, fewer sales, and less overall engagement.

When using media queries, one should keep in mind the behavior of all page elements, not just those that are being targeted, especially when using fluid grids, in which case as opposed to fixed dimensions the page will be fully filled at any given moment, increasing and decreasing content size proportionally.

Since widths are set in percentages, graphical elements i. For images, one solution is as follows:. Other elements should be dealt with in similar ways. Such a discussion should include maximum facilitated usage, element importance based on visible page regions , facilitated reading, and intuitive navigation. Among these categories, one of the most important components is content width adjustment. For example, the so-called fluid grid systems have set elements, i.

In this way, all elements in the responsive web design system automatically adjust with the size of the page. Therefore, I will just mention some major frameworks that support such behavior: Bootstrap , Unsemantic , and Brackets.

Until recently, website optimization was a term exclusively reserved for customization of functionality based on different web browsers. Alongside the inevitable struggle with different browser standards that we face today, this term now assumes adapting to devices and screen sizes with responsive web design as well.

This second approach is described as mobile first responsive design and is quite often the best approach to follow. The view for the very smallest devices is quite often a simple single column of content, much as it appears in normal flow.

This means that you probably don't need to do a lot of layout for small devices — order your source well and you will have a readable layout by default. The below walkthrough takes you through this approach with a very simple layout. In a production site you are likely to have more things to adjust within your media queries, however the approach would be exactly the same.

We've made no layout changes, however the source of the document is ordered in a way that makes the content readable. This is an important first step and one which ensures that if the content were to be read out by a screen reader, it would be understandable.

This simple layout also works well on mobile. If we view the layout in Responsive Design Mode in DevTools we can see that it works pretty well as a straightforward mobile view of the site. Open step 1 in the browser, or view the source. If you want to follow on and implement this example as we go, make a local copy of step1.

From this point, start to drag the Responsive Design Mode view wider until you can see that the line lengths are becoming quite long, and we have space for the navigation to display in a horizontal line. This is where we'll add our first media query. We'll use ems, as this will mean that if the user has increased their text size, the breakpoint will happen at a similar line-length but wider viewport, than someone with a smaller text size.

This CSS gives us a two-column layout inside the article, of the article content and related information in the aside element. We have also used flexbox to put the navigation into a row. Open step 2 in the browser, or view the source.

Lets continue to expand the width until we feel there is enough room for the sidebar to also form a new column. Inside a media query we'll make the main element into a two column grid. We then need to remove the margin-bottom on the article in order that the two sidebars align with each other, and we'll add a border to the top of the footer.

Typically these small tweaks are the kind of thing you will do to make the design look good at each breakpoint. Open step 3 in the browser, or view the source. If you look at the final example at different widths you can see how the design responds and works as a single column, two columns, or three columns, depending on the available width. This is a very simple example of a mobile first responsive design. If you look at the HTML source in the above example, you'll see the following element included in the head of the document:.

This is the viewport meta tag — it exists as a way control how mobile browsers render content. This is needed because by default, most mobile browsers lie about their viewport width. Non-responsive sites commonly look really bad when rendered in a narrow viewport, so mobile browsers usually render the site with a viewport width wider than the real device width by default usually pixels , and then shrink the rendered result so that it fits in the display.

This is all well and good, but it means that responsive sites are not going to work as expected. To remedy this, including a viewport meta tag like the one above on your page tells the browser "don't render the content with a pixel viewport — render it using the real device width instead, and set a default initial scale level for better consistency. There are a number of other options you can put inside the content attribute of the viewport meta tag — see Using the viewport meta tag to control layout on mobile browsers for more details.

Flexbox, Grid, and multi-column layout all give you ways to create flexible and even responsive components without the need for a media query. It's always worth considering whether these layout methods can achieve what you want without adding media queries. For example, you might want a set of cards that are at least pixels wide, with as many of these pixels as will fit into the main article.

This can be achieved with grid layout, using no media queries at all. Open the grid layout example in the browser, or view the source. Check out the support chart below:.

Brad, That line is actually correct. The numbers , and are larger and in red because they triggered the media query. The media query triggers based on screen width, which is So you always have to step back and ask, what is the actual device width that is being returned?

But given the media query in the min-width example, a screen width of will mean any styles in there will be ignored. Please read again and let us know if we can provide any further clarification. To our knowledge, the facts stated in this post are accurate.

Perhaps revising the example explanation by adding color:. Even though the minimum width to create the "true" state is px. Therefore, how can anything less than px trigger true? The first part of the equation is the width that is being returned from the device, the second is your min-width value. What you guys are saying is true, but got the wording to confusing. The specified is being compare with the device width as the reference. Therefore we are comparing the specified in the media query against the actual device width.

Notice how I switch specified and device width. You should change it to. This make things more clear because if you think in terms of a number line where 0 is the center and how big or small a number is determine how far it is from 0, then make the device width our 0. This is because device width is equal to than set number.

The examples were generated on actual devices using those media queries. Hi Everybody i am new in responsive web, Self learning to see tutorials and download demo and doing practice. Nobody doing my help in my country. I am struggling through changing my website to be more responsive and it helped me figure out media queries better. I however found this video which seems to explain it quite nicely. Seems I only get a response if I use one or the other.

But still yahoo email app is showing desktop layout and not the mobile layout. Your article however gave me exactly what I need for my current project — clear, concise and without all the usual overly-technical fluff — perfect! There is some debate about this already in the discussion above, but the bottom line is that this comment is just wrong:.
