- save the changes using the menu or CTRL-S shortcut
- then refresh the browser window
If that's not it, you might try sharing your entire workspace. Here's a video that explains how to make a workspace snapshot to share.

Front End Web Development Techdegree Student 9,429 PointsEverything seems to be right but just two small issues on item 3 and 7.
// 1: Set the text of the <h1> element
const h1 = document.querySelector('h1'); h1.textContent = "Working with the DOM";
// 2: Set the color of the <h1> to a different color h1.style.color = "orchid";
// 3: Set the content of the '.desc' paragraph //The content should include at least one HTML tag
/==========THE PROBLEM==============/ //SHOULD BE CONST WHEN DECLARING VARIABLES AND NOT CONT
/* cont desc = document.querySelector('.desc'); desc.innerHTML = "Having fun in the <strong>HOOD</strong>"; */
/==========THE SOLUTION==============/ const desc = document.querySelector('.desc'); desc.innerHTML = "Having fun in the <strong>HOOD</strong>";
// 4: Set the class of the <ul> to 'list' const list = document.querySelector('ul'); list.className = "list";
// 5: Create a new list item and add it to the <ul> const item = document.createElement('li'); item.innerHTML = "<input> Walk my fish"; list.appendChild(item);
// 6: Change all <input> elements from text fields to checkboxes const input = document.getElementsByTagName('input'); for (let i = 0; i < input.length ; i++) { input[i].type = 'checkbox'; };
// 7: Create a <button> element, and set its text to 'Delete' // Add the <button> inside the '.extra' <div>
/=======THE PROBLEM=======/ //REMOVE THE QUOTES ON 4TH LINE INSIDE THE PARENTHESIS
/const deleteButton = document.createElement('button'); deleteButton.textContent = "DeLeTe"; const extra = document.querySelector('.extra'); extra.appendChild('deleteButton');/
/==========THE SOLUTION===========/ const deleteButton = document.createElement('button'); deleteButton.textContent = "DeLeTe"; const extra = document.querySelector('.extra'); extra.appendChild(deleteButton);
// 8: Remove the '.extra' <div> element from the DOM when a user clicks the 'Delete' button const container = document.querySelector('.container'); deleteButton.addEventListener('click', () => { container.removeChild(extra); });

Also, when posting code, always use Markdown formatting to preserve the code's appearance.

231,269 PointsMaking a workspace snapshot would allow replication of your issue. Also, it would help if you explain exactly how what you are seeing differs from what you are expecting.
