If you need to append single element then just use appendChild() the usual way. var div document.querySelector ('div') var p document. Here is an example of how you would append a paragraph element to a div element. Using document.createDocumentFragment() is recommended if you do a lot of appendChild() one after the other. OK thx duri but I do know about auto-closing (elements with optional closing tags), my CSS in the comment above makes div in p display as the user would like but I would never suggest using that (unless no option to change HTML), to clarify.'validation' being important, HTML validation is usually a good first step as to why CSS will not display like you think it should without need to know. To append data to a div element using JavaScript, you would first need to select the element using a selector, then use the append () or appendChild () method to append data to the selected element. SectionCountdownSelector.appendChild(docFragment) // this appends the elem on your DOM ParagraphElement.innerHTML = 'inner text in the paragraph' // add text to p elemĭocFragment.appendChild(divElement) // append div elem to your fragmentĭivElement.appendChild(paragraphElement) // append p elem to div elem tAttribute('class', 'your-another-class') // assing a class to it I've included some optional JavaScript that will cause the tooltip to be displayed near the cursor. In your example you need to specify the parent by selecting it with a document.querySelector('.section-countdown') and assigning it to a const variable, for example const sectionCountdownSelector (if you are not planning on using babel use var instead).Įxample code below: const sectionCountdownSelector = document.querySelector('.section-countdown') // select your divĬonst docFragment = document.createDocumentFragment() // to not redraw DOM every timeĬonst divElement = document.createElement('div') // create a div elemĭtAttribute('class', 'your-desired-class') // assign a class to itĬonst paragraphElement = document.createElemet('p') // create a p elem Here's a pure CSS 3 implementation (with optional JS) The only thing you have to do is set an attribute on any div called 'data-tooltip' and that text will be displayed next to it when you hover over it. If you plan on appending many elements at once consider using document.createDocumentFragment() first, so that you don't redraw the DOM every time you append an element but instead you append it at the end, after every child node has been added. You can do that by using document.createElement(typeOfElem). This method requires you to first create a childNode that will be appended later. Another thing I like to do is creating an object and then looping thru the object and setting the styles like that because it can be tedious writing every single style one by one. To append elements into the DOM with JS you can use the element.appendChild(childNode) method.
