.typing{
display: inline-block;
width: 100%;
white-space:nowrap;
overflow:hidden;
-webkit-animation: type 2s steps(50, end) alternate;
animation: type 2s steps(50, end) alternate;
-webkit-animation-iteration-count: infinite; /* Chrome, Safari, Opera */
animation-iteration-count: infinite;
}
@keyframes type{
from { width: 0; }
}
@-webkit-keyframes type{
from { width: 0;  }
}
<style>
<div id="top" class="header">
<div class="text-center">
    <h1 class="typing"  >
<b>Find anything for your Business Instantly</b>
<b>Source >> Supply >> Grow your Business Online</b>
<b>Create your Home &amp; Global website online</b>
    </h1>        
</div>
</div>

我有3个粗体标签,它们在h1标签中,这里应该显示在一行中,作为一个接一个的粗体标签,如链接see this link : http://www.indiamart.com/所示

请任何人都可以帮助我.

@-webkit-keyframes typing {
    from { width: 0 }
    to { width:16.3em }
}

@-moz-keyframes typing {
    from { width: 0 }
    to { width:16.3em }
}

@-webkit-keyframes blink-caret {
    from, to { border-color: transparent }
    50% { border-color: black }
}

@-moz-keyframes blink-caret {
    from, to { border-color: transparent }
    50% { border-color: black }
}

body { font-family: Consolas, monospace; }

h1 { 
    font-size:150%;
    width:16.3em;
    white-space:nowrap;
    overflow:hidden;
    border-right: .1em solid black;
    
    -webkit-animation: typing 17s steps(30, end), /* # of steps = # of characters */
                        blink-caret 1s step-end infinite;
    -moz-animation: typing 17s steps(30, end), /* # of steps = # of characters */
                        blink-caret 1s step-end infinite;
}
