Issues Arising From Arbitrary-Element hover - Archive of obsolete content
for example: :hover {color: red;} this is equivalent to the css2 rule: *:hover {color: red;} ..which translates as "any element that is being hovered should have its foreground colored red." thus, hovering over paragraphs, tables, headings, and any other element in a document will cause text to become red.
... a common variant is to use a bare class and hover pseudo-class together, like this: .nav:hover {color: red;} in situations where the only instances of the class value nav are applied to hyperlinks, this will work fine.
...the most reliable fix is to add the anchor element to the selectors, like this: a:hover {color: red;} a.nav:hover {color: red;} in an attempt to avoid causing problems for legacy documents, browsers based on mozilla 1.0 and later (netscape 7+) include code that causes bare pseudo-classes to be restricted only to links if the document is rendered in "quirks" mode.

The box model - Learn web development
for styling borders, there are a large number of properties — there are four borders, and each border has a style, width and color that we might want to manipulate.
... you can set the width, style, or color of all four borders at once using the border property.
... to set the properties of each side individually, you can use: border-top border-right border-bottom border-left to set the width, style, or color of all sides, use the following: border-width border-style border-color to set the width, style, or color of a single side, you can use one of the most granular longhand properties: border-top-width border-top-style border-top-color border-right-width border-right-style border-right-color border-bottom-width border-bottom-style border-bottom-color border-left-width border-left-style border-left-color in the example below we have used various shorthands and longhands to create borders.
...the navigation below is displayed in a row using flexbox and we have added padding to the <a> element as we want to be able to change the background-color when the <a> is hovered.

How CSS works - Learn web development
again, the html is as follows: <p> let's use: <span>cascading</span> <span>style</span> <span>sheets</span> </p> let's suppose we apply the following css to it: span { border: 1px solid black; background-color: lime; } the browser will parse the html and create a dom from it, then parse the css.
... in the example below i have used the british english spelling for color, which makes that property invalid as it is not recognised.
... so my paragraph has not been colored blue.
... <p> i want this text to be large, bold and blue.</p> p { font-weight: bold; colour: blue; /* incorrect spelling of the color property */ font-size: 200%; } this behavior is very useful.

The HTML5 input types - Learn web development
color picker control colors are always a bit difficult to handle.
... a color control can be created using the <input> element with its type attribute set to the value color: <input type="color" name="color" id="color"> when supported, clicking a color control will tend to display the operating system's default color picking functionality for you to actually make your choice with.
... the following screenshot taken on firefox for macos provides an example: and here is a live example for you to try out: the value returned is always a lowercase 6-value hexidecimal color.
... note: color inputs are not supported in internet explorer.

Image gallery - Learn web development
example looks like this: the most interesting parts of the example's css file: it absolutely positions the three elements inside the full-img <div> — the <img> in which the full-sized image is displayed, an empty <div> that is sized to be the same size as the <img> and put right over the top of it (this is used to apply a darkening effect to the image via a semi-transparent background color), and a <button> that is used to control the darkening effect.
... if the class name is "dark", changes the <button> class to "light" (using setattribute()), its text content to "lighten", and the background-color of the overlay <div> to "rgba(0,0,0,0.5)".
... if the class name not "dark", changes the <button> class to "dark", its text content back to "darken", and the background-color of the overlay <div> to "rgba(0,0,0,0)".
... btn.setattribute('class', xxx); btn.textcontent = xxx; overlay.style.backgroundcolor = xxx; hints and tips you don't need to edit the html or css in any way.

Manipulating documents - Learn web development
as an example, try adding these lines to our ongoing example: para.style.color = 'white'; para.style.backgroundcolor = 'black'; para.style.padding = '10px'; para.style.width = '250px'; para.style.textalign = 'center'; reload the page and you'll see that the styles have been applied to the paragraph.
... if you look at that paragraph in your browser's page inspector/dom inspector, you'll see that these lines are indeed adding inline styles to the document: <p style="color: white; background-color: black; padding: 10px; width: 250px; text-align: center;">we hope you enjoyed the ride.</p> note: notice how the javascript property versions of the css styles are written in lower camel case whereas the css versions are hyphenated (e.g.
... backgroundcolor versus background-color).
... add the following inside your html <head>: <style> .highlight { color: white; background-color: black; padding: 10px; width: 250px; text-align: center; } </style> now we'll turn to a very useful method for general html manipulation — element.setattribute() — this takes two arguments, the attribute you want to set on the element, and the value you want to set it to.

Video and Audio APIs - Learn web development
first of all, notice the .controls styling: .controls { visibility: hidden; opacity: 0.5; width: 400px; border-radius: 10px; position: absolute; bottom: 20px; left: 50%; margin-left: -200px; background-color: black; box-shadow: 3px 3px 5px black; transition: 1s all; display: flex; } .player:hover .controls, player:focus .controls { opacity: 1; } we start off with the visibility of the custom controls set to hidden.
...src: url('fonts/heydings_controls-webfont.eot?#iefix') format('embedded-opentype'), url('fonts/heydings_controls-webfont.woff') format('woff'), url('fonts/heydings_controls-webfont.ttf') format('truetype'); font-weight: normal; font-style: normal; } button:before { font-family: heydingscontrolsregular; font-size: 20px; position: relative; content: attr(data-icon); color: #aaa; text-shadow: 1px 1px 0px black; } first of all, at the top of the css we use a @font-face block to import a custom web font.
... icon fonts are very cool for many reasons — cutting down on http requests because you don't need to download those icons as image files, great scalability, and the fact that you can use text properties to style them — like color and text-shadow.
... last but not least, let's look at the css for the timer: .timer { line-height: 38px; font-size: 10px; font-family: monospace; text-shadow: 1px 1px 0px black; color: white; flex: 5; position: relative; } .timer div { position: absolute; background-color: rgba(255,255,255,0.2); left: 0; top: 0; width: 0; height: 38px; z-index: 2; } .timer span { position: absolute; z-index: 3; left: 19px; } we set the outer .timer <div> to have flex: 5, so it takes up most of the width of the controls bar.

SVG Guidelines
invisible shapes there are two kinds of invisible shapes: the off-screen ones and the uncolored ones.
... on the other hand, the uncolored ones are easier to spot, since they usually come with styles making them invisible.
...pty tags, this may be obvious, but those are sometimes found in svgs unreferenced ids (usually on gradient stops, but also on shapes or paths) clip-rule attribute when the element is not a descendant of a <clippath> fill-rule attribute when the element is a descendant of a <clippath> unreferenced/unused clip paths, masks or defs (example) styling basics privilege short lowercase hex for colors don't use excessive precision for numeric values (usually comes from illustrator) use descriptive ids avoid inline styles and use class names or svg attributes examples here are some examples for excessive number precision: 5.000000e-02 → 0.05 (as seen here) -3.728928e-10 → 0 (as seen here) translate(0.000000, -1.000000) → translate(0, -1) (as seen here) as for descriptive id...
...you can also use svg grouping to avoid duplicating those attributes avoid introducing variants of the same file (color/style variants), and use sprites instead (with class names) default style values there's usually no need to set the default style value unless you're overriding a style.

...a: <div> <label for="fname">first name *: </label> <input id="fname" name="fname" type="text" required> <span></span> </div> to provide these indicators, we use the following css: input + span { position: relative; } input + span::before { position: absolute; right: -20px; top: 5px; } input:invalid { border: 2px solid red; } input:invalid + span::before { content: '✖'; color: red; } input:valid + span::before { content: '✓'; color: green; } we set the <span>s to position: relative so that we can position the generated content relative to them.
