Why is Bootstrap the go-to for web developers?

Image
Why is Bootstrap the go-to for web developers? Let’s break the advantages down into 8 parts: 1. Bootstrap’s Responsive Grid No more spending hours coding your own grid—Bootstrap comes with its own grid system predefined! Now, you can get straight to filling your containers with content. Defining custom breakpoints for each column is a snap using their extra small, small, medium, large, and extra large breaks. You can also simply stick to the default as it might already meet the needs of your site. 2. Bootstrap’s Responsive Images Bootstrap comes with its own code for automatically resizing images based on the current screen size. Just add the .img-responsive class to your images, and the predefined CSS rules take care of the rest. Let Bootstrap resize your images for you! It can even change the shape of your images with the addition of classes like img-circle and img-rounded, and that’s without going back and forth between the code and your design software. 3. B

How Does CSS Work

Image
          How Does CSS Work? CSS brings style to your web pages by interacting with HTML elements. Elements are the individual HTML components of a web page—for instance a paragraph—which in HTML might look like this: <p>This is my paragraph!</p> If you wanted to make this paragraph appear pink and bold to people viewing your web page through a web browser, you’d use CSS code that looks like this: p  {  color:pink;  font-weight:bold;  } In this case, “p” (the paragraph) is called the “selector”—it’s the part of CSS code specifying which HTML element the CSS styling will effect. In CSS, the selector is written to the left of the first curly bracket. The information between curly brackets is called a declaration, and it contains properties and values that are applied to the selector. Properties are things like font size, color, and margins, while values are the settings for those properties. In the example above, “color” and “font-weight” are both properties, and “p

What is CSS

Image
CSS stands for Cascading Style Sheets with an emphasis placed on “Style.” While HTML is used to structure a web document (defining things like headlines and paragraphs, and allowing you to embed images, video, and other media), CSS comes through and specifies your document’s style—page layouts, colors, and fonts are all determined with CSS. Think of HTML as the foundation (every house has one), and CSS as the aesthetic choices (there’s a big difference between a Victorian mansion and a mid-century modern home).

It is a device with sensors and actuators, for example : a robotic car, a camera, a PC.  Agent program  is an implementation of an agent function. An  agent func

What is machine learning

Image
This article discusses the categories of machine learning problems, and terminologies used in the field of machine learning. Types of machine learning problems There are various ways to classify machine learning problems. Here, we discuss the most obvious ones. 1. On basis of the nature of the learning “signal” or “feedback” available to a learning system Supervised learning : The computer is presented with example inputs and their desired outputs, given by a “teacher”, and the goal is to learn a general rule that maps inputs to outputs. The training process continues until the model achieves a desired level of accuracy on the training data. Some real life examples are: Image Classification:  You train with images/labels. Then in the future you give a new image expecting that the computer will recognize the new object. Market Prediction/Regression:  You train the computer with historical market data and ask the computer to predict the new price
