How to align a to the middle (horizontally/width) of the page [duplicate]

Answer 1

• Get the width of the screen.
• Then make margin left 25%
• Make margin right 25%

In this way the content of your container will sit in the middle.

Example: suppose that container width = 800px;

    

    
    


if ($("#myContent").parent === $("updatedContent"))
{
    $("#myContent").css({
        'left': '-(device-width/0.25)px';
        'right': '-(device-width/0.225)px';
    });
}
