            <p>Um servidor web é um software que processa solicitações via protocolo HTTP, enviando páginas web para os clientes (navegadores) em resposta a essas solicitações. Ele hospeda e serve conteúdo web, que pode incluir páginas HTML, imagens, vídeos, arquivos CSS, JavaScript, etc.</p>
            <p>Os servidores web desempenham um papel fundamental na disponibilização de sites e aplicativos web na internet.</p>

            <h2>Como instalar o Apache no Linux</h2>
            <p>O Apache é um dos servidores web mais populares e amplamente utilizados no mundo Linux. Abaixo estão os passos para instalar o Apache em uma distribuição Linux baseada no Debian (como Ubuntu):</p>
            <ol>
                <li>Abra o terminal.</li>
                <li>Atualize a lista de pacotes usando o comando: <code>sudo apt update</code>.</li>
                <li>Instale o Apache digitando: <code>sudo apt install apache2</code>.</li>
                <li>Aguarde enquanto o sistema baixa e instala o Apache.</li>
                <li>Depois que a instalação estiver concluída, o Apache será iniciado automaticamente. Você pode verificar o status do serviço digitando: <code>sudo systemctl status apache2</code>.</li>
                <li>Se o Apache estiver em execução, você verá uma saída indicando que o serviço está ativo e em execução.</li>
                <li>Para garantir que o Apache seja inicializado automaticamente no momento da inicialização do sistema, você pode digitar: <code>sudo systemctl enable apache2</code>.</li>
            </ol>
            <p>Após seguir esses passos, o Apache estará instalado e em execução no seu sistema Linux.</p>

  • Any HTML document must start with document declaration <!DOCTYPE html>
  • HTML documents begin with <html> and ends with </html>
  • Headings are defined with <h1> to <h6> where <h1> is the highest important heading and <h6> is the least important sub-heading.
  • Paragrahs are defined in <p>..</p> tag.
  • Links are defined in <a> tag.

    Example:

    <a href="https://onecompiler.com/html">HTML online compiler</a>
    
  • Images are defined in <img> tag, where src attribute consists of image name.

HTML Elements and Attributes

  • HTML element is everything present from start tag to end tag.
  • The text present between start and end tag is called HTML element content.
  • Anything can be a tagname but it's preferred to put the meaningful title to the content present as tag name.

  • Elements with no content are called empty elements.
  • Elements can have attributes which provides additional information about the element.
