Each item’s <var>label</var> is 0139 typeset in bold and is flush left, so that long labels continue into the 0140 first line of the item text. There must be at least one item; having 0141 none causes the LaTeX error ‘<samp>Something's wrong--perhaps a 0142 missing \item</samp>’. 0143 </p> 0144 <p>This example shows the environment used for a sequence of definitions. 0145 </p> 0146 <div class="example"> 0147 <pre class="example">\begin{definition} 0148 \item[lama] A priest. 0149 \item[llama] A beast. 0150 \end{definition} 0151 </pre></div> 0152 0153 <p>The labels ‘<samp>lama</samp>’ and ‘<samp>llama</samp>’ are output in boldface, with the 0154 left edge on the left margin. 0155 </p> 0156 <a name="index-_005citem"></a> 0157 <p>Start list items with the <code>\item</code> command (see <a href="_005citem.html#g_t_005citem">\item</a>). Use the 0158 optional labels, as in <code>\item[Main point]</code>, because there is 0159 no sensible default. Following the <code>\item</code> is optional text, which 0160 may contain multiple paragraphs. 0161 </p> 0162 <a name="index-bold-typewriter_002c-avoiding"></a> 0163 <a name="index-typewriter-labels-in-lists"></a> 0164 <p>Since the labels are in bold style, if the label text calls for a font 0165 change given in argument style (see <a href="Font-styles.html#Font-styles">Font styles</a>) then it will come 0166 out bold. For instance, if the label text calls for typewriter with 0167 <code>\item[\texttt{label text}]</code> then it will appear in bold 0168 typewriter, if that is available. The simplest way around this, in this 0169 example to get non-bold typewriter, is to use declarative style: 0170 <code>\item[{\tt label text}]</code>. Similarly, get the standard roman 0171 font with <code>\item[{\rm label text}]</code>. 0172 </p> 0173 <p>For other major LaTeX labelled list environments, see <a href="itemize.html#itemize">itemize</a> 0174 and <a href="enumerate.html#enumerate">enumerate</a>. Unlike those environments, nesting 0175 <code>description</code> environments does not change the default label; it is 0176 boldface and flush left at all levels. 0177 </p> 0178 <p>For information about list layout parameters, including the default 0179 values, and for information about customizing list layout, see 0180 <a href="list.html#list">list</a>. The package <samp>enumitem</samp> is useful for customizing 0181 lists. 0182 </p> 0183 <p>This example changes the description labels to small caps. 0184 </p> 0185 <div class="example"> 0186 <pre class="example">\renewcommand{\descriptionlabel}[1]{% 0187 {\hspace{\labelsep}\textsc{#1}}} 0188 </pre></div> 0189 0190 0191 0192 0193 <hr/><div class='referenceinfo'> <a href='https://latexref.xyz/'> <i>Unofficial LaTeX2e reference manual</i></a></div> 0194 </body> 0195 </html>
