Learn Development at Frontend Masters. I enjoyed Erik D. In it, his Rule 4 is: Learn the methods of overlaying text on images. I thought we could take a look at all his points, code them up, and note anything that comes up technically. You could darken it in an image editing program, or, with CSS, overlay a transparent color.

And while a black overlay is simplest and most versatile, you can certainly find colored overlays as well. Just one. I find this to be true as well, at least when trying to be classy whatsoever.

Garbage magazines tend to go with yellow.

And by the way, if you wanted to cover the entire screen like this, but then be able to scroll down for more, you could set the top area as having a height of vh units. Browser support varies a bit there. This is dead simple and very reliable. Whip up a mildly-transparent black rectangle and lather on some white text.

If the overlay is opaque enough, you can have just about any image underneath and the text will still be totally legible. With a single line of text, this is easy.

A surprisingly good way for making overlaid text legible is to blur part of the underlying image. One way to do that is to to have a section of the area inherit the same background, position it the same fixed attachment is one waythen blur it. You could blur it enough it works OK:.

Responsive images was, in a sense, just catching up to what CSS could already do. One image for 1x displays, a larger image for 2x displays. If we wanted to do that same thing, only as a background-image in CSS, we could do:. There is a difference here, though. The attribute and value provide information about what is available and the browser decides what is best at the moment. Or at least, it couldif browsers chose to implement it that way.

With a media query, what is declared shall be. According to the still in draft spec :. The image-set function allows an author to ignore most of these issues, simply providing multiple resolutions of an image and letting the UA decide which is most appropriate in a given situation. You pair it with srcsetwhich provides known widths, so the browser can make a choice. The information in the markup above gives the browser what it needs to figure out the best image for it.

It now also knows it will be displaying this image at vw. So it has to pick between the two images provided. It does some math.

Creating Responsive Shapes With Clip-Path And Breaking Out Of The Box

Now say it was a 2x display. That doubles the amount of pixels needed to show the images, so the math is:. How about a 1x display with a px viewport? This is kinda weird and tricky to write out in CSS. If we just think about 1x displays, we end up with logic like…. In this exact case, a 2x display, even at a really narrow width like px, still requires px make that 1. The complexity of this skyrockets the more breakpoints sizes and the more provided images.

This kind of thing is a fairly straight-forward conversion to media queries. The exact media queries are right there to copy:.IO site. I spent a few hours while on CodePen, and after I picked my jaw up from the floor, I put together a collection of my favorite CodePen. IO demos. Draw Worm is an eye-catching, canvas-based animation that creates branches; better yet, the animation follows the mouse, creating more branches. The value change is highlighted by opacity shine and animating around the circle.

A great feat without JavaScript! Trail is another cavas-based masterpiece which creates different color rays that follow the user's mouse at an accelerated rate. Even color is that you can see grey lines stay in the background, representing vapor trails. This single-element demo composes the Google Chrome logo using :before and :afteras well as a number of CSS gradients. Hover over the logo and it shrinks and rotates too!

What's more impressive is that it's not just a spinning set of elements -- the elements warp into different shape patterns too. Linjer starts out as a pulsating set of colored lines, until you click around the lines! The animations intensify near the clicks and the rippling becomes more meaningful. You'd be surprised at how little CSS is used to accomplish this task. Social Switchbook is probably the most practical of the demos provided in this post. The effect provides a keyring-style set of elements which animate into display as you hover over each.

No JavaScript involved.

Canvas Fireworks is a neat and responsive demo, shooting fireworks to the position at which you click. There's even a control panel to all you to customize speed, color, and accuracy of the firework. The guys on Breaking Bad sell one hell of a drug, and Tim Pietrusky must have also beed on one when he created this excellent SVG-powered tribute to the shows opening credits.If the width property is set to a percentage and the height is set to "auto", the image will be responsive and scale up and down:.

Notice that in the example above, the image can be scaled up to be larger than its original size. A better solution, in many cases, will be to use the max-width property instead.

If the background-size property is set to "contain", the background image will scale, and try to fit the content area. However, the image will keep its aspect ratio the proportional relationship between the image's width and height :.

If the background-size property is set to "cover", the background image will scale to cover the entire content area. Notice that the "cover" value keeps the aspect ratio, and some part of the background image may be clipped:. A large image can be perfect on a big computer screen, but useless on a small device. Why load a large image when you have to scale it down anyway? To reduce the load, or for any other reasons, you can use media queries to display different images on different devices.

You can use the media query min-device-widthinstead of min-widthwhich checks the device width, instead of the browser width. Then the image will not change when you resize the browser window:. You set up different sources, and the first source that fits the preferences is the one being used:. The srcset attribute is required, and defines the source of the image. The media attribute is optional, and accepts the media queries you find in CSS media rule.

This is optional. The technique will work without this. This dimension will have us covered on most widescreen computer monitors currently being sold in the market, but at the expense of serving up a 1. And also, the image dimension is excessive on small-screen devices more on this further down in this tutorial.

However, this technique will also work on any block-level element such as a div or a form. If the width and height of your block-level container is fluid, then the background image will always scale to cover the container entirely. And, as we all know, when we scale up an image from its natural dimensions, the image quality degrades in other words, pixelation occurs. When an image is scaled up above its natural dimensions, image quality is affected. So that the background image is always centered in the viewport, we declare:.

When this happens, a scroll bar will appear. To do this, we set the background-attachment property to fixed. One thing you could do is download the demo and then play around with the positional property values e. For small screens, I used Photoshop to proportionally resize the original background image down to xpx and I also ran it through Smush. Doing this reduced the file size down from KB to KB. For a KB payload, I would normally only subject users to it if the file had the potential to add a significant improvement in UX, because of the huge mobile web performance trade-off.

The media query is set at a max-width: px breakpoint, which in our case means that if the browser viewport is greater than px, it will serve the larger background image file. The downside of using the media query above is that if you resize your browser window from, for example, px width down to px width or vice versayou will momentarily see a flicker while the smaller or bigger background image loads up. In addition, because some small devices can render more pixels — for example, iPhone 5 with its retina display can render xpx — the smaller background image will be pixelated.

As you resize the screen, it goes from three columns, to two columns, to a single column on mobile. Another great example of that is this really weird musical side project of minewhere I arrange all the songs as if they're a Spotify album listing. The only real difference between those two is that one has margins, and the other doesn't.

In this quick article, I'm going to go over how to create a responsive grid of images like that with flexbox.

Make sure before starting to include some sort of reset, or at least set box-sizing: border-box and margin: 0 to the body. More about all that, if you're not sure. Now we can get started on the grid.

We'll start off by making the mobile page - mobile first layout means utilizing min-width media queries for bigger screen sizes.

The grid class will be the flex wrapping container. For mobile, everything is one column, so it doesn't need to be defined as flex yet. Inside that, I'm going to make a cell and place an image inside of that. We'll make the image responsive by putting a max-width on it.

I'm going to choose px as the width to start showing the mid-screen view. We want the images to show up in rows of two now. The grid wrapping container is defined as a flex element, which will wrap in the direction of a row horizontal.

At pxI'm going to show the desktop view, which will display the images in rows of three. This gallery has no padding or spacing between the images. You have to make some slight adjustments if you want to add space between all the images.

The best part about this grid is it can be easily looped. If you're not familiar with WordPress, here's the article to get you started. Instead of using a WordPress gallery plugin, you can pull images by category from the media gallery.I am struggling to come up with an ideal solution to handle a responsive hero image with vertically centered text overlay.

Does anyone have any tested methods that work well? Should the image be an inline image or CSS background image? I tried with the code below but the vertical centering only seems to work with a fixed height…. A Codepen example of your specific design would be really helpful but this might get you started. Wow this is a great thread! Rems are great for consistent measurements throughout the page and avoid the compounding issues of em measurements. It does all depends on the layout in hand though as you may want to build your page so that each element has a relationship with the parent element rather than the root element.

As usual with CSS there is no one right way to do something because it does depend on the job in hand. Ok I see.

Some good examples here, at some point though it feels like the text should drop down below the image otherwise it may not work or the image becomes too small behind the text. Yes that will be an issue whatever you do as it will depend on the amount of text you have.

In my example above I allowed the text to produce a scrollbar so that it was still readable if this happened. This topic is empty. Viewing 9 posts - 1 through 9 of 9 total. March 17, at pm March 18, at am March 18, at pm March 19, at pm GroovyMotion Participant.
