HTML provides the structural framework of a webpage, CSS enhances the visual design, and Javascript adds interactivity and dynamism.
1.Elements:-HTML documents consist of elements represented by tags enclosed in angle brackets (< and >). Elements can nest inside one another and contain text, images, links, and other elements.
2.Tags:-HTML elements are defined using tags, which typically come in opening (<tag>) and closing (</tag>) pairs surrounding the element's content. However, some tags like the <img> image tag are self-closing and do not need a closing tag.
3.Attributes:-Attributes contain extra information about an element and appear within the opening tag. They use name-value pairs, like src="image.jpg" in an <img> tag, to define the image source.
4.Structure:-HTML documents have a standardized structure that begins with a <!DOCTYPE> declaration to specify the document type. The <html> element contains <head> and <body> sections to organize metadata and page content, respectively. Within these sections, HTML elements define the page's title, links, text, media, and other content.
5.Heading:-HTML offers six heading levels, ranging from <h1> for the highest level to <h6> for the lowest, to structure and organize content on a web page.
6.Pharagraph:-The <p> tag creates paragraph breaks in HTML documents. Each <p> tag indicates the start of a new paragraph, separating blocks of text.
7.Links:-The <a> tag creates hyperlinks that allow users to navigate between web pages. The href attribute specifies the destination URL for the link.
8.Lists:-HTML supports ordered and unordered lists through the <ol> and <ul> tags, respectively; list items within those lists are defined using the <li> tag.
9.Images:-The <img> tag inserts images into HTML documents. The src attribute specifies the image's URL, while the alt attribute provides alternative text for accessibility.
10.Forms:-HTML offers various form elements, including <input>, <textarea>, and <select>, to build interactive forms that let users submit data to a web server.
11.Tables:-To display tabular data on a web page, tables are created using the HTML tags <table>, <tr> for table rows, <td> for table cells, and <th> for table headers.
12.Sematic HTML:-Semantic HTML refers to using HTML elements that provide meaning about the content, such as <header>, <footer>, <nav>, <article>, and <section>. It enhances accessibility and search engine optimization by clearly labeling page sections.
To build well-structured and accessible web pages with HTML, you must first understand key HTML concepts. A great way to start learning HTML is by using an online compiler, which lets you practice writing code, test projects, and view results instantly. Online compilers make it easy to get hands-on experience with HTML as you build your skills.
