How can I place two headings next to each other using CSS?

问题

<h5>Category</h5><h6>auto</h6>

places Category and auto on separate lines, like this:

How can I place them both on the same line, like this?

Category auto

回答1:

h(n) elements are 'block' elements, which means they will grow to take all available horizontal space. This also means they will push anything "right" of them down to the next line.

One easy way to accomplish this is to set their display to inline:

<style>
    h5, h6 {display:inline;}
</style>

Note that inline-block is not supported in all browsers.

You can also float block elements, but that can become a sticky issue as floating can be fairly complex. Stick with inline for cases like this.

回答2:

<h5 style="display:inline-block;">Category</h5>
<h6 style="display:inline-block;">auto</h6>

You must change the display mode of the elements. H tags are rendered as BLOCK elements by default. To override this behavior add the following style definitions to your website or CSS

h5,h6 { display: inline; } 

You can also decide to let them "float" next to each other you can do that via:

h5,h6 { float: left; } 

Please note that floating only works on block elements (so using both styles will perform no float because inline elements cannot float).
