How to set a border for an HTML div tag

I am trying to define a border around a div tag in HTML. In some browsers the border does not appear.

Here is my HTML code:

<div id="divActivites" name="divActivites" style="border:thin">
    <textarea id="inActivities" name="inActivities" style="border:solid">
    </textarea> 
</div> 

How do I set a border for an HTML div tag?

Solution 1:

Try being explicit about all the border properties. For example:

border:1px solid black;

See Border shorthand property. Although the other bits are optional some browsers don't set the width or colour to a default you'd expect. In your case I'd bet that it's the width that's zero unless specified.

Solution 2:

can use

border-width:2px;
border-style:solid;
border-color:black;

or as shorthand

border: 2px solid black

Solution 3:

As per the W3C:

Since the initial value of the border styles is 'none', no borders will be visible unless the border style is set.

In other words, you need to set a border style (e.g. solid) for the border to show up. border:thin only sets the width. Also, the color will by default be the same as the text color (which normally doesn't look good).

I recommend setting all three styles:

style="border: thin solid black"

Solution 4:

I guess this is where you are pointing at ..

<div id="divActivites" name="divActivites" style="border:thin">
    <textarea id="inActivities" name="inActivities" style="border:solid">
    </textarea> 
</div> 

Well. it must be written as border-width:thin

Here you go with the link (click here) check out the different types of Border-styles

you can also set the border width by writing the width in terms of pixels.. (like border-width:1px), minimum width is 1px.
