<input type="time"> - HTML: Hypertext Markup Language
this is simple enough, with the label and input as we've seen before, but with the addition of a <p> element with a <span> to display the value of the time input: <form> <label for="starttime">start time: </label> <input type="time" id="starttime"> <p> value of the <code>time</code> input: <code> "<span id="value">n/a</span>"</code>.
...when this happens, the contents of the <span> are replaced with the new value of the input element.
... var starttime = document.getelementbyid("starttime"); var valuespan = document.getelementbyid("value"); starttime.addeventlistener("input", function() { valuespan.innertext = starttime.value; }, false); when a form including a time input is submitted, the value is encoded before being included in the form's data.

UI pseudo-classes - Learn web development
since form inputs don't directly support having generated content put on them (this is because generated content is placed relative to an element's formatting box, but form inputs work more like replaced elements and therefore don't have one), we will add an empty <span> to hang the generated content on: <div> <label for="fname">first name: </label> <input id="fname" name="fname" type="text" required> <span></span> </div> the immediate problem with this was that the span was dropping onto a new line below the input because the input and label are both set with width: 100%.
... to fix this we style the parent <div> to become a flex container, but also tell it to wrap its contents onto new lines if the content becomes too long: fieldset > div { margin-bottom: 20px; display: flex; flex-flow: row wrap; } the effect this has is that the label and input sit on separate lines because they are both width: 100%, but the <span> has a width of 0 so can sit on the same line as the input.
...we create it using this css: input + span { position: relative; } input:required + span::after { font-size: 0.7rem; position: absolute; content: "required"; color: white; background-color: black; padding: 5px 10px; top: -26px; left: -70px; } we set the <span> to position: relative simply so that we can set the generated content to position: absolute and position it relative to the <span> rather than the <body> (the generated content acts as though it is a child node of the element it is generated on, for the purposes of positioning).

in the following example we are setting a minimum value of week 01, 2017 and a maximum value of week 52, 2017: <form> <label for="week">what week would you like to start?</label> <input id="week" type="week" name="week" min="2017-w01" max="2017-w52"> <span class="validity"></span> </form> here's the css used in the above example.
...we had to put the icons on a <span> next to the input, not on the input itself, because in chrome the generated content is placed inside the form control, and can't be styled or shown effectively.
... div { margin-bottom: 10px; position: relative; } input[type="number"] { width: 100px; } input + span { padding-right: 30px; } input:invalid+span:after { position: absolute; content: '✖'; padding-left: 5px; } input:valid+span:after { position: absolute; content: '✓'; padding-left: 5px; } the result here is that only weeks between w01 and w52 in 2017 will be seen as valid and be selectable in supporting browsers.

How can we design for all types of users? - Learn web development
suppose we wanted a base font size of 16px and an h1 (main heading) at the equivalent of 32px, yet if within the h1 we find a span with the subheading class, it too must be rendered at the default font size (usually 16px).
... here is the html we're using: <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>font size experiment</title> </head> <body> <h1>this is our main heading <span class="subheading">this is our subheading</span> </h1> </body> </html> a percent-based css will look like this: body { font-size:100%; } /* 100% of the browser's base font size, so in most cases this will render as 16 pixels */ h1 { font-size:200%; } /* twice the size of the body, thus 32 pixels */ span.subheading { font-size:50%; } /* half the size of the h1, thus 16 pixels to come back to the original size */ the same problem expressed with ems: body { font-size:1em; } /* 1em = 100% of the browser's base font size, so in most cases this will render as 16 pixels */ h1 { font-size:2em...
...; } /* twice the size of the body, thus 32 pixels */ span.subheading { font-size:0.5em; } /* half the size of the h1, thus 16 pixels to come back to the original size */ as you can see, the math quickly gets daunting when you have to keep track of the parent, the parent's parent, the parent's parent's parent, and so on.

How whitespace is handled by HTML, CSS, and in the DOM - Web APIs
to make it easier, we’ve illustrated all spaces with ◦, all tabs with ⇥ , and all line breaks with ⏎: this example: <h1>◦◦◦hello◦⏎ ⇥⇥⇥⇥<span>◦world!</span>⇥◦◦</h1> is rendered in the browser like so: hidden example <h1> hello <span> world!</span> </h1> the <h1> element contains only inline elements.
... an inline element (the <span>, which contains a space, and the word "world!").
... inside this context, whitespace character processing can be summarized as follows: first, all spaces and tabs immediately before and after a line break are ignored so, if we take our example markup from before and apply this first rule, we get: <h1>◦◦◦hello⏎ <span>◦world!</span>⇥◦◦</h1> next, all tab characters are handled as space characters, so the example becomes: <h1>◦◦◦hello⏎ <span>◦world!</span>◦◦◦</h1> next, line breaks are converted to spaces: <h1>◦◦◦hello◦<span>◦world!</span>◦◦◦</h1> after that, any space immediately following another space (even across two separate inline elements) i...

HTMLElement.offsetLeft - Web APIs
however, for inline-level elements (such as span) that can wrap from one line to the next, offsettop and offsetleft describe the positions of the first border box (use element.getclientrects() to get its width and height), while offsetwidth and offsetheight describe the dimensions of the bounding border box (use element.getboundingclientrect() to get its position).
... therefore, a box with the left, top, width and height of offsetleft, offsettop, offsetwidth and offsetheight will not be a bounding box for a span with wrapped text.
... example var colortable = document.getelementbyid("t1"); var toleft = colortable.offsetleft; if (toleft > 5) { // large left offset: do something here } this example shows a 'long' sentence that wraps within a div with a blue border, and a red box that one might think should describe the boundaries of the span.

DOMTokenList.remove() - Web APIs
return value undefined examples in the following example we retrieve the list of classes set on a <span> element as a domtokenlist using element.classlist.
... we then remove a token from the list, and write the list into the <span>'s node.textcontent.
... first, the html: <span class="a b c"></span> now the javascript: let span = document.queryselector("span"); let classes = span.classlist; classes.remove("c"); span.textcontent = classes; the output looks like this: to remove multiple classes at once, you can supply multiple tokens.
... the order you supply the tokens doesn't have to match the order they appear in the list: let span2 = document.getelementsbytagname("span")[0] let classes2 = span.classlist; classes2.remove("c", "b"); span2.textcontent = classes; specifications specification status comment domthe definition of 'remove()' in that specification.

<p id="para-01"> <span>first span</span> </p> <script> var p01 = document.getelementbyid('para-01'); console.log(p01.firstchild.nodename); </script> in the above, the console will show '#text' because a text node is inserted to maintain the whitespace between the end of the opening <p> and <span> tags.
... another #text node is inserted between the closing </span> and </p>tags.
... if this whitespace is removed from the source, the #text nodes are not inserted and the span element becomes the paragraph's first child.
... <p id="para-01"><span>first span</span></p> <script> var p01 = document.getelementbyid('para-01'); console.log(p01.firstchild.nodename); </script> now the console will show 'span'.

ARIA annotations - Accessibility
the semantics for this have long been available in html, via the <ins> and <del> elements: <p>freida’s pet is a <del>black cat called luna</del><ins>purple tyrannosaurus rex called tiny</ins>.</p> with the new additions, you now have new roles available to provide the same semantics, should you be unable to use <ins> and <del> elements for some reason: <p>freida’s pet is a <span role="deletion">black cat called luna</span><span role="insertion">purple tyrannosaurus rex called tiny</span>.</p> however, this often isn’t enough — when you’ve got a content change like the one above that involves an insertion and a deletion, there is no way for a screenreader user to work out if the two are related or not.
... this is the job of role="suggestion", which should be set on an element wrapping both of them like so: <p>freida’s pet is a <span role="suggestion"><span role="deletion">black cat called luna</span><span role="insertion">purple tyrannosaurus rex called tiny</span></span>.
... </p> we could even provide an information box saying who made the suggestion and when, and associate it with the suggestion via aria-details: <p>freida’s pet is a <span role="suggestion" aria-details="comment-source"><span role="deletion">black cat called luna</span><span role="insertion">purple tyrannosaurus rex called tiny</span></span>.

my adjacent block level elements sit on new lines below me.</p> <p>by default we span 100% of the width of our parent element, and we are as tall as our child content.
...because of margin collapsing, we are separated by the width of one of our margins, not both.</p> <p>inline elements <span>like this one</span> and <span>this one</span> sit on the same line as one another, and adjacent text nodes, if there is space on the same line.

Document and website structure - Learn web development
for cases like these, html provides the <div> and <span> elements.
... <span> is an inline non-semantic element, which you should only use if you can't think of a better semantic text element to wrap your content, or don't want to add any specific meaning.
... for example: <p>the king walked drunkenly back to his room at 01:00, the beer doing nothing to aid him as he staggered through the door <span class="editor-note">[editor's note: at this point in the play, the lights should be down low]</span>.</p> in this case, the editor's note is supposed to merely provide extra direction for the director of the play; it is not supposed to have extra semantic meaning.

Manipulating documents - Learn web development
create three new elements — a list item (<li>), <span>, and <button>, and store them in variables.

Getting from Content to Layout
to give a trivial example of when this might be necessary, consider: "<span>foo <div></div> bar</span>".
... separate frames are created for the pre and post-div parts of the <span>.
... if the <div> is removed, the frame construction code merges those frames by examining the parent frame, destroying the two frames created for the <span>, and creating one unified frame for the text content.

Aggregate view - Firefox Developer Tools
type this is the default view, which looks something like this: it groups the things on the heap into types, including: javascript objects: such as function or array dom elements: such as htmlspanelement or window strings: listed as "strings" javascript sources: listed as "jsscript" internal objects: such as "js::shape".
...this page simply runs a script that creates a large number of dom nodes (200 htmldivelement objects and 4000 htmlspanelement objects).
... so in the example above, we can see that we made 4002 allocations, accounting for 89% of the total heap, in createtoolbarbutton(), at alloc.js line 9, position 23: that is, the exact point where we create the <span> elements.

AbstractRange - Web APIs
in order to set a range endpoint within the text of an element, be sure to find the text node inside the element: let startelem = document.queryselector("p"); let endelem = startelem.queryselector("span"); let range = document.createrange(); range.setstart(startelem, 0); range.setend(endelem, endelem.childnodes[0].length/2); let contents = range.clonecontents(); document.body.appendchild(contents); this example creates a new range, rng, and sets its starting point to the third child node of the first element whose class is elementclass.
... the end point is set to be the middle of the first child of the span, and then the range is used to copy the contents of the range.
... ranges and the hierarchy of the dom in order to define a range of characters within a document in a way that is able to span across zero or more node boundaries, and which is as resilient as possible to changes to the dom, you can't simply specify the offset to the first and last characters in the html.

DOMTokenList.add() - Web APIs

Box alignment in CSS Grid Layout - CSS: Cascading Style Sheets
if an item spans more than one grid track, as further space is added between the tracks, that item needs to become large to absorb the space.
...you can see how items 1 and 2, which span two row tracks have taken on extra height as they gain the additional space added to the gap between those two tracks: justifying the grid tracks on the row axis on the inline axis, we can use justify-content to perform the same type of alignment that we used align-content for in the block axis.
...this once again causes tracks which span more than one column track to gain extra space: * {box-sizing: border-box;} .wrapper { border: 2px solid #f76707; border-radius: 5px; background-color: #fff4e6; } .wrapper > div { border: 2px solid #ffa94d; border-radius: 5px; background-color: #ffd8a8; padding: 1em; color: #d9480f; } .wrapper { display: grid; grid-template-columns: repeat(3, 100px); grid-template-rows: repeat(3, 100px); height: 500px; width: 500px; grid-gap: 10px; grid-template-areas: "a a b" "a a b" "c d d"; align-content: space-between; justify-content: space-around; } .item1 { grid-area: a; } .item2 { grid-area: b; } .item3 { grid-area: ...

Subgrid - CSS: Cascading Style Sheets
for example, if you use grid-template-columns: subgrid and the nested grid spans three column tracks of the parent, the nested grid will have three column tracks of the same size as the parent grid.
...as the item spans five column tracks, this means that the subgrid has five column tracks.
...so the column tracks behave as a regular nested grid, but the rows are tied to the two tracks that the child spans.

margin-trim - CSS: Cascading Style Sheets
asic usage once support is implemented for this property, it will probably work like so: when you've got a container with some inline children and you want to put a margin between each child but not have it interfere with the spacing at the end of the row, you might do something like this: article { background-color: red; margin: 20px; padding: 20px; display: inline-block; } article > span { background-color: black; color: white; text-align: center; padding: 10px; margin-right: 20px; } the problem here is that you'd end up with 20px too much spacing at the right of the row, so you'd maybe do this to fix it: span:last-child { margin-right: 0; } it is a pain having to write another rule to achieve this, and it is also not very flexible.
