CSS菜单居中

标签： javascript jquery html css

可能有一些非常明显的东西我不知道但是我似乎无法将我找到的这个模板菜单集中在一起。按中心我的意思是中心在屏幕内对齐。它通常是保证金：0px auto;和显示：块;但我没有运气。

请参阅jsfiddle链接。如果它没有正确显示，请拖动“结果”＆＃39;选项卡左侧。

非常感谢

只需在代码下面更改css文件：
的 CSS 

#cssmenu {
  width: auto;
  margin: 0px auto;
  font-family: arial, sans-serif;
  line-height: 1;
  background: #fff;
    text-align:center;
}

尝试改变：

 #cssmenu {
      width: 100%;
    text-align: center;
}
#cssmenu,
#cssmenu ul,
#cssmenu ul li,
#cssmenu ul li a,
#cssmenu #menu-button {
display:inline-block
}

希望这会对你有所帮助：

(function($) {

  $.fn.menumaker = function(options) {
      
      var cssmenu = $(this), settings = $.extend({
        title: "Menu",
        format: "dropdown",
        sticky: false
      }, options);

      return this.each(function() {
        cssmenu.prepend('<div id="menu-button">' + settings.title + '</div>');
        $(this).find("#menu-button").on('click', function(){
          $(this).toggleClass('menu-opened');
          var mainmenu = $(this).next('ul');
          if (mainmenu.hasClass('open')) { 
            mainmenu.hide().removeClass('open');
          }
          else {
            mainmenu.show().addClass('open');
            if (settings.format === "dropdown") {
              mainmenu.find('ul').show();
            }
          }
        });

        cssmenu.find('li ul').parent().addClass('has-sub');

        multiTg = function() {
          cssmenu.find(".has-sub").prepend('<span class="submenu-button"></span>');
          cssmenu.find('.submenu-button').on('click', function() {
            $(this).toggleClass('submenu-opened');
            if ($(this).siblings('ul').hasClass('open')) {

            }
            else {

            }
          });
        };

        if (settings.format === 'multitoggle') multiTg();
        else cssmenu.addClass('dropdown');

        if (settings.sticky === true) cssmenu.css('position', 'fixed');

        resizeFix = function() {

            cssmenu.find('ul').show();
          }

          if ($(window).width() <= 768) {
            cssmenu.find('ul').hide().removeClass('open');
          }
        };
        resizeFix();
        return $(window).on('resize', resizeFix);

      });
  };
})(jQuery);

(function($){
$(document).ready(function(){

$(document).ready(function() {
  $("#cssmenu").menumaker({
    title: "Menu",
    format: "multitoggle"
  });

  $("#cssmenu").prepend("<div id='menu-line'></div>");

var foundActive = false, activeElement, linePosition = 0, menuLine = $("#cssmenu #menu-line"), lineWidth, defaultPosition, defaultWidth;

$("#cssmenu > ul > li").each(function() {
  if ($(this).hasClass('active')) {
    activeElement = $(this);
    foundActive = true;
  }
});

if (foundActive === false) {
  activeElement = $("#cssmenu > ul > li").first();
}

defaultWidth = lineWidth = activeElement.width();

defaultPosition = linePosition = activeElement.position().left;

menuLine.css("width", lineWidth);
menuLine.css("left", linePosition);

$("#cssmenu > ul > li").hover(function() {
  activeElement = $(this);
  lineWidth = activeElement.width();
  linePosition = activeElement.position().left;
  menuLine.css("width", lineWidth);
  menuLine.css("left", linePosition);
}, 
function() {
  menuLine.css("left", defaultPosition);
  menuLine.css("width", defaultWidth);

答案 2 :(得分：1)

我会将div#cssmenu元素包装在div#container中。这样，您就可以在容器display: inline-block;上创建菜单text-align: center;并使用div。

请参阅https://jsfiddle.net/dtb08ng1/2/上的更新的JSfiddle。

更新

为了让它发挥作用我添加的新CSS如下：

#container {
  text-align: center;
  width: 100%;
  background: #000000;
}
#cssmenu {
  display: inline-block;
  …
}

我做的唯一HTML更改是将div#cssmenu包装如下：

…
<div id="container">
  <div id="cssmenu">
  …
  </div>
</div>
…
