- The border styles in the list are: solid, dashed and dotted. - By clicking on “Create the styled paragraph“, you should insert the text ( in the text area) in a paragraph below with the selected style properties. - By clicking on search (after putting a word to look for it), the paragraph that appeared below should highlight every matched word in it. If it is not exist it should display below that the word does not exist. - By clicking on “Clear Search” you should remove all the highlights that appear on it from the last searching process. - You should display the web page in a very similar way to the above suggestion. كيف ممكن اعدل على كود اني ابحث عن كلمة موجوده ب text area وكيف ممكن اعمل شكل كما في صوره <!DOCTYPE html> <html> <head> <style> aside { float: left; padding: 20px; width: 70%; height: 300px } section:after { content: ""; display: table; clear: both; } footer { padding: 10px; text-align: center; color: white; } </style> </head> <body> <header> <textarea id="TextEditor" rows="30" cols="50" placeholder="Copy and Paste a text here ..."></textarea> </header> <section> <h1>Styling a paragraph</h1> <label for="textcolor">Text Color:</label> <input type="color" id="textcolor" value="#ff0000"><br> <label for="backgroundcolor">Background Color:</label> <input type="color" id="backgroundcolor" value="#ff0000"><br> <input type="radio" value="1" checked="checked">With Border<br> <input type="radio" value="0">Without Border<br> <label for="bordercolor">Border Color:</label> <input type="color" id="bordercolor" value="#ff0000"><br> <input type="button" value="Create the styled button"> <aside> <h1>Searching for a text</h1> </aside> </section> <footer> <div id="Results"></div> </footer> <script> document.querySelector('input[type = button]').addEventListener("click", function(){ document.getElementById("Results").innerHTML = document.getElementById("TextEditor").value; if(document.querySelector('input[type = radio]:checked').value === 1){ document.getElementById("Results").style.border = "thick solid "+document.getElementById("bordercolor").value; } document.getElementById("Results").style.color = document.getElementById("textcolor").value; document.getElementById("Results").style.backgroundColor = document.getElementById("backgroundcolor").value; }); </script> </body> </html>

هي كود html ..ممكن مساعده بكود JavaScript: <!DOCTYPE html> <html> <body> <h1 >Welcome Back</h1> <hr> <br> <p> Hello class </p> <p> No more Covid19 </p> <p> Be safe </p> <p> Best wishes </p> <h2 >See you soon</h2> <hr> <br> <input type="text" > <input type="button" value="Insert header"> <br><br> <input type="color" > <input type="button" value="Apply to background"> <br><br> <input type="text" > <input type="button" value="Insert header"> <br><br> <input type="button" value="Show paragraphs"> </body> </html> Copy and paste the previous code and do the following: 1- When the user writes inside the text box and clicks Insert to header, this will change the header of the page with the written text. 2- When the user selects a color and clicks Apply, the background color of the page should be changed. 3- When the user clicks on a paragraph, this will change the background color of the paragraph to yellow. 4- When the user double clicks on any paragraph, this will hide the paragraph. 5- Clicking on Show all paragraphs, this will show all the paragraphs in the page. When the user clicks on any paragraph ( the color of the background should be yellow), when the user clicks on another paragraph, only one paragraph should have the background color been set to yellow.
