 In Selenium, locating strategies are techniques used to identify web elements on a page so that actions (like click, type, etc.) can be performed on them. Selenium provides multiple locators to interact with HTML elements. Below is a complete list of Selenium locators, with details , HTML examples , and code snippets for each. 🔍 1. ID ✅ Best when the element has a unique ID. 🔧 HTML: <input id="username" type="text"> 🧪 Selenium (Java): driver.findElement(By.id("username")).sendKeys("testuser"); 🔍 2. Name ✅ Useful when the element has a unique name attribute. 🔧 HTML: <input name="password" type="password"> 🧪 Selenium: driver.findElement(By.name("password")).sendKeys("mypassword"); 🔍 3. Class Name ⚠️ Use only when class is unique or combined with other locators. 🔧 HTML: <button class="login-button">Login</button> 🧪 Selenium: driver.findEleme...

  🌐 How HTML Web Page Hosting Works: Server, Domain, URL & Database Explained Creating a website is more than just writing HTML code. Behind every page you see on the internet, there's a network of servers, domain names, and often a database managing content. Let’s break it down step by step. 🧾 1. What is Web Hosting? Web hosting is a service that stores your website’s files (HTML, CSS, JavaScript, images, etc.) on a server , making them accessible on the internet. 💡 Think of it like this: Your HTML files are like the furniture in a house. A web host (server) is the house. The internet is the road system that connects people to your house. 🖥️ 2. What is a Web Server? A web server is a computer that: Stores website files (HTML, CSS, images, etc.). Responds to requests from browsers. Sends back the right content via HTTP/HTTPS protocols . Example: When you visit https://example.com/about.html , here's what happens: The browser con...

 To help you understand locators in Selenium , it's crucial to grasp more detailed HTML concepts. Selenium uses HTML tags and attributes to find (or "locate") elements on a web page. Below is an expanded article section with HTML knowledge specifically useful for identifying and locating elements in Selenium . 🔍 Understanding HTML for Locating Elements in Selenium Selenium interacts with web elements using locators , which are based on HTML structure and attributes. Here's what you need to know about HTML to use Selenium effectively: 1. 🆔 Using the id Attribute id is a unique identifier for an HTML element — the most preferred locator. <input type="text" id="username"> Selenium Locator Example: driver.findElement(By.id("username")); 2. 👨‍👨‍👧‍👦 Using the class Attribute class is used to apply styles, and can also be used to locate elements (but it's not unique). <button class="btn login">Log...

📄 Building a Basic HTML Web Page: Paragraphs, Formatting, Images, Links, and Tables Creating a web page with HTML involves combining various elements to structure and display content effectively. Below are the essential features you can add to an HTML page, each explained with code examples. 1. ✅ Adding Paragraphs to the HTML Web Page Paragraphs are added using the <p> tag. <p>This is a paragraph of text on a web page.</p> <p>Here is another paragraph explaining a new topic.</p> 2. 💬 Adding Bold Text Bold text helps highlight important words or phrases. Use the <b> or <strong> tag. <p>This is a <b>bold</b> word.</p> <p>This is also <strong>strongly emphasized</strong> text.</p> 3. 🔠 Displaying Headings (H1 to H6) HTML provides six heading levels, from <h1> (largest) to <h6> (smallest). <h1>Main Heading</h1> <h2>Sub Heading</h2> <h3>S...

HTML for Selenium (Part 3) – HTML Structure   In the previous posts, we have understood the below HTML basics: > What is HTML? > HTML Elements, Tags, Attributes & Enclosed Text In this article, I am going to explain the structure of HTML. Before I start explaining the structure of HTML, you need to first understand that, almost all tags in HTML have both Start and End Tags. Start Tag: > Syntax: <TagName> > Example: <h1> End Tag: > Syntax: </TagName> > Example: </h1> Both Start and End Tags are used together in HTML as shown below: Example:  <h1>  This is a Bigger Size Heading Text  </h1> In the above example, <h1> is the start tag which starts before the heading text starts and </h1> is the end tag which starts after the heading text. Now, you understood the start and end tags. Let’s move to the structure of HTML. HTML for Selenium – HTML Structure Follow the below steps to understand the...
