when page is loaded i need to pop this window automatically and 2nd option by click

can some one help me

回答1:

One option is to use javascript and add the extra rules for new class.

Css:

.modal:target:before, .modal.loaded:before { ... }
.modal:target .modal-dialog, .modal.loaded .modal-dialog { ... }

Js:

$( document ).ready( function() {
    $('.modal').addClass('loaded');
    $('.btn-close, .btn').click( function() {
        $('.modal').removeClass('loaded');
    });
});

A css only solution is to :target url for closing popup.

.modal:target:before {
    display: none;
}
.modal:before {
    content:"";
    display: block;
    background: rgba(0, 0, 0, 0.6);
    position: fixed;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    z-index: 10;
}
.modal .modal-dialog {
    background: #fefefe;
    border: #333333 solid 1px;
    border-radius: 5px;
    margin-left: -200px;
    position: fixed;
    left: 50%;
    z-index: 11;
    width: 360px;
    -webkit-transform: translate(0, 0);
    -ms-transform: translate(0, 0);
    transform: translate(0, 0);
    -webkit-transition: -webkit-transform 0.3s ease-out;
    -moz-transition: -moz-transform 0.3s ease-out;
    -o-transition: -o-transform 0.3s ease-out;
    transition: transform 0.3s ease-out;
    top: 20%;
}
.modal:target .modal-dialog {
    top: -100%;
    -webkit-transform: translate(0, -500%);
    -ms-transform: translate(0, -500%);
    transform: translate(0, -500%);
}
