How To Make An Animation Size Relative In Dreamweaver

Scaling our websites and applications so that they look great on every screen can be difficult. A big portion of that difficulty can exist trying to get specific components, specially ones that accept pieces that accept to stay a sure size (like animations), to look good regardless of the screen size. In this post, we'll embrace how to help continue our responsive animations sized the fashion we want them.

Before we go into specific techniques, there are a couple basic guidelines we desire to keep in mind:

Guidelines for scaling responsive animations

1. Size the animations based on a container

Whether nosotros're using responsive or adaptive scaling (see below), we should attempt to size animations based on the container's sizing. In responsive scaling this is simple plenty, but in adaptive scaling nosotros have to wait to element (container) queries. The only exception is if we know that in every circumstance the chemical element is going to be positioned and sized relative to the viewport. Even so, it might be wise to size each slice based on a container in example we modify our minds subsequently.

There have been times where I've finished polishing an blitheness exactly the way I want only to realize that information technology only works for that item screen size. Those times have included making mistakes similar using absolute units (like px), merely viewing it in one screen size, using responsive units but failing to check farthermost dimensions, and a couple other occasions where I had to go back and completely refactor my approach. Sizing animations relative to the parent elements helps prevent that from happening, as does the following point:

2. Know the environments in which information technology will be used

Will the blitheness be a module that is repeated across multiple parts of your application? Is it only going to be used for a page loader initially? Does it need to scale at all? Keeping this in heed can assist determine the method in which an animation should exist scaled and go on you from wasting effort.

Now, let'due south look at the three about important ways that we tin can scale animations: scaling with responsive units, proportional scaling, and adaptive scaling.

Scaling with responsive units

Size pieces based on the parent

When we utilise responsive units like % or em, our animations automatically resize themselves based on the parent considering their values alter equally their parent's do.

In the instance of percentages, the kid'due south width value is set by the parent's value for the belongings, multiplied past the pct value assault the child.
In the instance of emsouth, it looks at the parent's font-size which determines the child's size values, multiplied by the number of ems.

This allows us to brand certain that each piece of our responsive animation retains the beliefs we want with respect to each other.

Sizing containers based on the viewport

From there, if we size our containers relative to the viewport, our responsive pieces will and so end up resizing themselves based on the viewport as well.

Nosotros could use percents to size our containers based on the viewport, but that often requires setting something like html, body { height: 100%; } and making sure that the parent is sized with respect to the torso, which may not always be the case with nesting. Calculation this new dominion can too touch other fashion changes.

Alternatively, we can use viewport units, which sizes the container based on the viewport regardless of how deeply it is nested. One matter to keep in mind is that support for viewport units is not perfect, though it'due south definitely in a state where it can be used for most projects.

I tend to use solely responsive units as a scalar for animations when it's a really simple blitheness, such as this illusion. Most the fourth dimension information technology requires a pairing of responsive units with an arroyo from below to proceed the animation proportional.

Proportional scaling

In that location are three principal means we tin can keep our responsive animation proportional while scaling information technology.

1. Size based on the width

To keep an chemical element sized based on the width of the container, we can use the following approach:

          .container {   height: 0;   padding-top: 100%; }

Come across the Pen Infinite Mountains CSS past Zach Saucier (@Zeaklous) on CodePen.

Even so, if you're sizing your container based on the viewport, a more straightforward approach would be to use vw similar then, though it doesn't reach every bit far back regarding support.

2. Size based on the superlative

We can also size our container using the height by using vh as seen in this demo, but it is the least-used technique that I've seen. The only time I can recall doing something similar this myself is when I used responsive units to create this loader, but fifty-fifty so I didn't use a container or viewport units.

3. Size based on the smaller dimension

Sizing based on the larger dimension is by far the about common fashion I size my responsive animations, peculiarly my visualizations, because I well-nigh always want all of my responsive animations to be seen entirely. This method ensures that that happens.

          .container {   max-width: 100vh;   max-height: 100%;   margin: 0 auto;   overflow: subconscious; } .container::before {   content: "";   display: block;   margin-top: 100%; }

See the Pen Swirling dots by Zach Saucier (@Zeaklous) on CodePen.

This technique doesn't make use of the vmax unit of measurement, then whatever browser that supports viewport units (dorsum to IE9) can employ information technology. Still, it does make use of a pseudo element (unless you want to use a existent chemical element) which should be kept in mind.

If yous are scaling the container on the viewport itself and can employ viewport units, it'south very simple to size based on the larger dimension. All you need is:

          .container {   width: 100vmin;   meridian: 100vmin; }

This arroyo can exist washed merely when the animation is sized with respect to the viewport, non some smaller container.

Adaptive scaling

Adaptive scaling is switching between variations at specific breakpoints. Meet Geoff Graham's CSS-Tricks article on the distinction between responsive and adaptive scaling.

At times nosotros may want at to the lowest degree part of our responsive animations to change how they're sized at a detail screen size. This is virtually commonly done when text or thin lines are used, though sometimes it'south too applicable when at that place are a lot of intricacies that would await busy when made smaller. Logos are probably the most commonly adapted elements considering they need to be precise.

There's no one way to make something adaptive, merely I arroyo it in the aforementioned manner I exercise responsive design: past scaling my animation until something starts to expect ugly, then add a breakpoint to fix what looks ugly.

Sometimes it's advisable to mix responsive pieces with adaptive ones, such as in the Pen beneath. The summit part is responsive merely the text is adaptive to prevent text scaling from becoming ugly during in-between font sizes.

A annotation on SVG

SVG tin make use of any of the approaches outlined above. Most commonly, I treat SVG similar a modular blitheness and brand sure my SVG is sized by the SVG chemical element itself, generally treating information technology as a container based on the larger dimension, as covered in a higher place. This fashion it makes use of the vector nature of SVGs, allowing it to scale to be equally large as it needs to be.

For more information on how to calibration SVG specifically, cheque out Amelia Bellay-Royds' post on scaling SVG components here on CSS-Tricks or Sara Soueidan's Codrops post on making SVG responsive.

Make it look great in all contexts

With a scrap of planning, animations tin work but as well at small sizes as they exercise at big sizes. Don't employ pixel units, and make sure every width, peak, and distance value are defined based on ane or two variables based on the container/viewport dimensions or by font size.
