How can I ad a Line under the Headline?

Hi there,

Any chance you can link us to the site in question?

You can use the private information field.

Hi Ying,

Ihabe send my website url

Give this CSS a try:

h2.entry-title {
    text-decoration: underline;
}

Let me know :)

Hi Ying,
thanks for your answer and vor the Code ...
But I meant a dividing line from the left side of the box to the right. Under the headline.
That was probably put a little wrong by me. Sorry...
And for all boxes in Sidebar...

Do you mean like this?

If so, try this CSS instead:

h2.entry-title {
    border-bottom: 2px solid grey;
    padding-bottom: 10px;
}

thats for sidebar headlines too???
And if i do open the post, it doesn´s work unter the headline...

Do you want it apply to the sidebar headline too? I'm confused.

Yes i Want this Line for headline on Sidebar and Post in all few´s....
If i do open the post, it doesn´s work unter the headline…
Sorry

So you want it everywhere even for pages? If so, try this:

h1, h2 {
    border-bottom: 2px solid grey;
    padding-bottom: 10px;
}

Thank you for your patience...
It works as it should now ;-)
