Css Selector For Mac
Note that before Firefox 48, the breadcrumbs toolbar was at the top of the markup pane. Searching Starting in Firefox 45, the Page Inspector's search box matches all markup in the current document and in any frames. To start searching the markup, click in the search box to expand it or press Ctrl + F, or Cmd + F on a Mac. As you type, an autocomplete popup shows any class or ID attributes that match the current search term: Press Up and Down to cycle through suggestions, Tab to choose the current suggestion, then Enter to select the first node with that attribute. If you just enter the search term without selecting an autocomplete value, then the search term will be applied to the full text of the document, including all attribute names and values and the text content of nodes.
To cycle through matches, press Enter. From Firefox 48 onwards you can cycle backwards through matches using Shift + Enter. HTML tree The rest of the pane shows you the page's HTML as a tree (this UI is also called the Markup View). Just to the left of each node is an arrow: click the arrow to expand the node. If you hold the Alt key while clicking the arrow, it expands the node and all the nodes underneath it.
Moving the mouse over a node in the tree highlights that element in the page. Nodes that are not visible are shown faded/desaturated.
This can have different reasons like using or that the element doesn't have any dimensions. From Firefox 53 onwards there is an ellipsis shown between the opening and closing tag of an element when the node is collapsed if it has larger contents.
Before Firefox 53, it was impossible to determine if a collapsed node had any children. Now children are indicated in the tree with this icon. Custom element definition When you open the Inspector on a page that includes custom elements, you can view the class definition for the custom element in the Debugger:. Inspect the element. Click on the word custom The source for the element's class will be displayed in the Debugger. Whitespace-only text nodes Web developers don’t write all their code in just one line of text.
They use white space such as spaces, returns, or tabs between their HTML elements because it makes markup more readable. Usually this white space seems to have no effect and no visual output, but in fact, when a browser parses HTML it will automatically generate anonymous text nodes for elements not contained in a node. This includes white space (which is after all a type of text). If these auto generated text nodes are, browsers will give them a non-zero width and height. Then you will find strange gaps between elements, even if you haven’t set any margin or padding on them. Since Firefox 52, the Inspector displays these whitespace nodes, so you can see where the gaps in your markup come from.
Whitespace nodes are represented with a dot: and you get an explanatory tooltip when you hover over them: To see this in action, see the demo at. Shadow roots Any shadow roots present in the DOM are exposed in the HTML page, in the same manner as the regular DOM. The shadow root is signified by a node named #shadow-root — you can click its expansion arrow to see the full contents of the shadow DOM, and then manipulate the contained nodes in a similar way to other part of the page's DOM (although with a limited featureset — you can't, for example, drag and drop or delete shadow DOM nodes). If a shadow DOM contains a 'slotted' element (an element with a slot attribute after it has been inserted inside a element — see for an explanation of how these are used), the 'slotted' element will be shown inside its corresponding element, with a 'reveal' link alongside it. Clicking the 'reveal' link will highlight the element with the slot attribute as it exists outside the shadow DOM This is very useful when you've got a element and you can't find the source of its content.
Note: Shadow DOM inspection was implemented in Firefox 61, but is currently hidden behind the dom.webcomponents.shadowdom.enabled pref. It will be turned on when are made available in the platform, which is currently looking like Firefox 63. Element popup context menu You can perform certain common tasks on a specific node using a popup context menu. To activate this menu, context-click the element.
The menu contains the following items — click on the links to find the description of each command in the:. Attributes. Copy. Paste.
These options only appear in certain contexts, for example the 'Open File in Style-Editor' option only appears when you context-click over the top of a link to a CSS file. Context menu reference. Note: The context menu was significantly reorganised from Firefox 49 onwards, to make it more compact. Don't worry if your menu structure differs slightly to that shown above — the same options will still be available. Copy the inner HTML for the element.

You'll see a text box in the HTML pane: You can add any HTML in here: changing the element's tag, changing existing elements, or adding new ones.
