would take up 100% of the available space, as it is a block level element. For each type or pseudo-element in a matching selector, add 0-0-1 to the weight value. This means I need to correctly set rules inside corresponding media queries to adjust the calc() method. In the next article, we'll take a look at how images, media, and form elements are treated in CSS. I'll read about inherit. When that password doesn't have focus, the specificity weight remains at 0-1-0. Ive been able to actually use it in production in certain scenarios already. If you have important information to share, please, http://codepen.io/ggilmore/pen/d8fc7309e1fc387f8965e66674ac031c. Again, this is the intrinsic size of the element its size is defined by its content. even JavaScript will not be enough to offer complete control of placing controls on a page. Like colorize inputs based on the numbers they contain. For example I use this approach to define vars which hold variations of a main color. Create a separate, short style sheet containing only important declarations specifically overriding any important declarations you were unable to remove. BCD tables only load in the browser with JavaScript enabled. The only way to override inline styles is by using !important. We have given the image in the example below a border so that you can see the extent of its size as defined in its file. For example, .box {width: 350px; border: 10px solid black;} renders a box that is 350px wide, with the area for content being 330px wide. Content box height: 80px */, /* Total width: 160px Find centralized, trusted content and collaborate around the technologies you use most. It displays the total value as the size of the element, thereby ignoring the actual size you assigned to the div. Does the policy change for AI-generated content affect users who (want to) How to set element's width according the text inside? "800px": "auto"); Forget about expressions they will only give you headaches and you are correct that they are non-standard. Depending on how you add it, you can add some, a lot, or no specificity, as shown below: No matter the order, the heading will be green because that rule is the most specific. The CSS calc() make it much easier to build fluid, responsive layouts. If you want set two elements the same width and you know what that width will be before hand then you can setup a class like, .ImageAndThumbnailWidth This is the default behaviour of the box-sizing property. The values of both come from the parameter in the list of parameters that has the highest specificity. Is "different coloured socks" not correct? This isnt exactly what you are looking for though is it? Media queries allow you to apply CSS styles depending on a device's general type (such as print vs. screen) or other characteristics such as screen resolution or browser viewport width. Why is it "Gaudeamus igitur, *iuvenes dum* sumus!" I put an image in a fixed height/width wrapper and tried to do something like this: Both FF and Chrome interpret it as -25%. You are right, Luciano, it is not strictly necessary. The above explanations on specificity should be helpful in avoiding using the flag and removing it altogether when encountered. Well, these cases are doable with older techniques. None of your examples appear to work properly in Firefox, because it still doesnt support the unprefixed version of the box-sizing property. To achieve what is done in the demo, you could just do: Demo: http://codepen.io/skimberk1/pen/jdbli. You can circumvent the problem using an intermediary: CSS variables, which is the only data "outside" the curly brackets, as it were. This can lead to a sticky situation if you want an element to naturally resize as its parent element or window dimensions change.

This is the initial and default value as specified by the CSS standard. They themselves don't add any weight to the specificity equation. Why do some images depict the same constellations differently? In the example below, we have used the same image three times. The selector with the greater value in the ID column wins no matter what the values are in the other columns. To me The weight is determined by the number of selectors of each weight category in the selector matching the element (or pseudo-element).

might as well update the style directly with the js. Shame to Webkit. If the numbers in the CLASS and ID columns in competing selectors are the same, the TYPE column becomes relevant. Heres a real world example. Is there a way to calc(div's height - some unit)? It's a little bit gimmick but it can be done with pure CSS.

The code below centers the text below the image, and if there is too much text it starts to the left of the left edge of the image and ends to the right of the right edge of the image. As an example, if you were to set width: 100% on an image, and its intrinsic width was smaller than its container, the image would be forced to stretch and become larger, causing it to look pixelated. Therefore the size of this
