Listes en HTML

Il existe trois types de listes en HTML : les listes ordonnées, les listes non ordonnées et les listes de définitions.

1. Une liste ordonnée est une liste d'éléments marqués de chiffres. Elle utilise

  • et est incluse dans la balise

      <p style="margin:0px; padding:0px; background-color:rgb(245,245,245)"><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">ol</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">开始部分</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">次要部分</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">结尾部分</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">ol</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span></p>

      2. Une liste non ordonnée est un groupe d'éléments marqués de points noirs, qui sont inclus dans la balise

        (listes non ordonnées) en utilisant

        .

        <p style="margin:0px; padding:0px; background-color:rgb(245,245,245)"><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">ul</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">关于主题</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">关于形式</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">关于内容</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">ul</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span></p>

        3. La liste de définitions représente sémantiquement la combinaison d'éléments et de leurs commentaires. Elle commence par la balise

        dt> (titre de la définition ), la définition des éléments de liste personnalisée commence par
        (description de la définition).

        <p style="margin:0px; padding:0px; background-color:rgb(245,245,245)"><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dl</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dt</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">CSS</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dt</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dd</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">CSS概念</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dd</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dd</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">CSS应用</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dd</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dd</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">CSS hacks</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dd</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">dl</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span></p>

        Sémantiquement parlant, les trois ensembles de balises correspondent à différentes listes avec des significations : les listes non ordonnées conviennent à un ordre non-niveau parmi les membres La situation de relation ; la liste ordonnée convient à la situation où il existe une relation séquentielle entre chaque élément ; la liste de définitions est utilisée pour un nom de terme correspondant à plusieurs définitions ou à plusieurs noms de termes avec la même définition, ou uniquement pour le nom du terme. ou seulement la définition, ou c'est-à-dire que le nombre de

        et
        n'est pas limité, et la relation correspondante n'est pas limitée.

        CSS pour la liste

        L'attribut CSS le plus important pour la liste est l'attribut list-style, sa syntaxe est la suivante :

        list-style:list-style-image||list-style-position||list-style-type

        list-style-image peut définir l'image utilisée avant la liste, liste -style- La valeur de l'attribut position inclut l'extérieur et l'intérieur ; l'extérieur est la valeur par défaut. La marque de l'élément de liste est placée à l'extérieur du texte à ce moment-là, et elle s'enroulera autour du texte à l'extérieur du texte. à l’intérieur du texte et aligné autour du texte.

        L'attribut CSS le plus important de la liste est l'attribut list-style. Sa syntaxe est la suivante :

        list-style-image peut définir l'image utilisée devant le. list, list-style- La valeur de l'attribut position inclut l'extérieur et l'intérieur ; l'extérieur est la valeur par défaut. La marque de l'élément de liste est placée à l'extérieur du texte à ce moment-là, et elle enveloppera le texte à l'extérieur de la liste. l'élément est pivoté à l'intérieur du texte et aligné autour du texte.

        list-style:list-style-image||list-style-position||list-style-type

        list-style-position est à l'extérieur

        若列表外标签

            的padding-left设置为0,且list-style-position为outside时,列表符号将不会显示,如上例中ul添加padding-left:0;将显示如下:




            list-style-type为列表显示类型 ,它共有9种常见属性值:


            • disc:默认值。实心圆

            • circle:空心圆

            • square:实心方块

            • decimal:阿拉伯数字

            • lower-roman:小写罗马数字

            • upper-roman:大写罗马数字

            • lower-alpha:小写英文字母

            • upper-alpha:大写英文字母

            • none:不使用项目符号

            我们可以看到,三种不同列表实际上只是list-style-type默认值不一样而已,通过设置list-style-type即可实现不同显示效果。





            列表之间的嵌套


            列表嵌套的html书写是不少人容易犯的错误,经常写错格式是这样的:

            <p style="margin:0px; padding:0px; background-color:rgb(245,245,245)"><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">ul</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">男性</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">ol</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">女性<br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">女孩子</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">姑娘</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important">大妈</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">ol</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">li</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span><span style="margin:0px; padding:0px; line-height:1.5!important"><br></span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"></</span><span style="margin:0px; padding:0px; color:rgb(128,0,0); line-height:1.5!important">ul</span><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important">></span></p>

            这里包括两处错误:一是

              后不允许直接跟文字,二是这里的文字“女性”应当在第二个
            • 后。正确格式如下:

              使用适合的标签进行合理的嵌套可以实现很多复杂的布局,比如常见的tab标签、滑动门等完全不需要使用js操作DOM即可完成,而且实现简单,语义性强。例如还有这篇文章定义列表dl打造图文并茂的CSS列表元素。

              下例以文章列表为例,html如下:


              <p style="margin:0px; padding:0px; background-color:rgb(245,245,245)"><span style="margin:0px; padding:0px; color:rgb(0,0,255); line-height:1.5!important"><</span><span style="margin:0px;
