Html – Add border-bottom to table row

csshtmlhtml-table

I have a table of 3 by 3. I need a way to add a border for the bottom of every row tr and give it a specific color.

First I tried the direct way, i.e.:

<tr style="border-bottom:1pt solid black;">

But that didn't work. So I added CSS like this:

tr {
border-bottom: 1pt solid black;
}

That still didn't work.

I would prefer to use CSS because then I don't need to add a style attribute to every row.
I haven't added a border attribute to the <table>. I hope that that is not affecting my CSS.

Add border-collapse:collapse to your table rule:

table { 
    border-collapse: collapse; 
}

Example

table {
  border-collapse: collapse;
}

tr {
  border-bottom: 1pt solid black;
}

<table>
  <tr><td>A1</td><td>B1</td><td>C1</td></tr>
  <tr><td>A2</td><td>B2</td><td>C2</td></tr>
  <tr><td>A2</td><td>B2</td><td>C2</td></tr>
</table>

The approach you suggest is not guaranteed to give you the result you're looking for - what if you had a tbody for example:

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
</table>

You would end up with the following:

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
  <tr>...</tr>
</table>

I would therefore recommend this approach instead:

$('#myTable tr:last').after('<tr>...</tr><tr>...</tr>');

You can include anything within the after() method as long as it's valid HTML, including multiple rows as per the example above.

Update: Revisiting this answer following recent activity with this question. eyelidlessness makes a good comment that there will always be a tbody in the DOM; this is true, but only if there is at least one row. If you have no rows, there will be no tbody unless you have specified one yourself.

DaRKoN_ suggests appending to the tbody rather than adding content after the last tr. This gets around the issue of having no rows, but still isn't bulletproof as you could theoretically have multiple tbody elements and the row would get added to each of them.

Weighing everything up, I'm not sure there is a single one-line solution that accounts for every single possible scenario. You will need to make sure the jQuery code tallies with your markup.

I think the safest solution is probably to ensure your table always includes at least one tbody in your markup, even if it has no rows. On this basis, you can use the following which will work however many rows you have (and also account for multiple tbody elements):

$('#myTable > tbody:last-child').append('<tr>...</tr><tr>...</tr>');

Html – How to align content of a div to the bottom

Relative+absolute positioning is your best bet:

#header {
  position: relative;
  min-height: 150px;
}

#header-content {
  position: absolute;
  bottom: 0;
  left: 0;
}

#header, #header * {
  background: rgba(40, 40, 100, 0.25);
}

<div id="header">
  <h1>Title</h1>
  <div id="header-content">And in the last place, where this might not be the case, they would be of long standing, would have taken deep root, and would not easily be extirpated. The scheme of revising the constitution, in order to correct recent breaches of it, as well as for other purposes, has been actually tried in one of the States.</div>
</div>

But you may run into issues with that. When I tried it I had problems with dropdown menus appearing below the content. It's just not pretty.

Honestly, for vertical centering issues and, well, any vertical alignment issues with the items aren't fixed height, it's easier just to use tables.

Example: Can you do this HTML layout without using tables?
