A question about line

[larryvc]

The question is:
In html,if i use <h1>context</h1> or <p>context</p> the system will add a empty line above and under the context.

If i don't want the empty line,how can i get rid of them?

can i change some properties about <h1> to make it don't add the empty line automatically?

<span style="font-size: 34px; font-weight: bold">context</span>123123123

thank you,but it seems that span can control the properties of context only,are there some others can control the whole line about context?

such as this sentence:
<span style="font-size: 15pt;
color: #f5f3f0; background-color: #333333;
font-family: arial, helvetica;
text-align: center
font-weight: bold" class="SeviceDesc">
context
</span>

it can change the properties of the context only,the other area except the context in the line will not be changed.
if i want set the background-color of the whole line of the context,how to do that?

请问有没有能够只控制一行的属性，比如说改变一行的背景色,<h1>会自动加行，谢谢了
