Drop down with CSS arrow

blog post about css menu with arrow

Here’s a quick one about how to create a drop-down UI element with an arrow via CSS. The aim is to create a menu that has drop-down sub-menus. Each drop-down should have an arrow that points up towards the parent element.

Here’s the HTML to structure the menu:

<div class="menu">
  <div class="menu-item">
    <span>Menu Item</span>
    <div class="drop-down-menu">
      <p>Sub-item</p>
      <p>Sub-item</p>
      <p>Sub-item</p>
    </div>
  </div>
  
  <div class="menu-item">
    <span>Menu Item 2</span>
  </div>
  
  <div class="menu-item">
    <span>Menu Item 3</span>
    <div class="drop-down-menu">
      <p>Sub-item</p>
      <p>Sub-item</p>
      <p>Sub-item</p>
    </div>
  </div>
  
</div>

I nest the sub-menu within the parent item, and use CSS to show it when a user mouses-over:

.menu-item:hover .drop-down-menu{
  display: block;
}

I line the menu-items in a row by setting display to ‘inline-block’. This is preferred over just ‘inline’, so that their height property is respected. This is important because I will create space between the parent item and sub-menu. If the two elements don’t actually overlap, then the hover state will be lost, closing the drop-down. See what I mean:

Drop down menu with CSS
The sub-menu element overlaps with the parent item, so that the hover state is not lost.

I also set the parent item position to relative, so that the drop-down will be absolutely positioned respective to it.

.menu-item{
  cursor: pointer;
  height: 50px;
  display: inline-block;
  position: relative;
}

Since the menu items have a height larger than the actual content, I apply borders to a child span within them:

.menu-item:first-child span{
  border:none;
}
.menu-item span{
  border-left: 1px solid black;
  padding: 0 10px;
}

The sub-menu styling is straight-forward. I set it to display: none, set a width, add a border and padding, and position it absolutely. Its top value pushes it off of the parent item a bit. Setting a left value to zero ensures that it will be aligned with its parent. (If you don’t set a left value, multiple sub-menus will all stack under the very first parent item.)

.drop-down-menu{
  display: none;
  width: 100px;
  position: absolute;
  background: white;
  border: 1px solid #301B46;
  padding: 20px;
  top: 40px;
  left: 0px;
}


The next step is building the arrow in the drop-down menu. The challenge is making the arrow’s border blend seamlessly with the container’s border. The illusion is achieved by overlapping the :before and :after pseudo-elements.

The triangle shape that forms the arrow is achieved by giving  a bottom border to an element with no height or width. This code pen animation does a phenomenal job of explaining the idea: https://codepen.io/chriscoyier/pen/lotjh

The drop-down’s :before element creates the white triangle that is the heart of the arrow itself. This also creates the gap in the sub-menu’s actual top border

The :after element creates another triangle that is behind and slightly above the first one – creating the illusion of a border that connects just right with the menu’s.

The illusion can be better revealed by manipulating the position and border-width of these pseudo-elements in the inspector.

Here is the code I used for those pseudo elements:

.drop-down-menu:before {
  content: "";
  position: absolute;
  border-color: rgba(194, 225, 245, 0);
  border: solid transparent;
  border-bottom-color: white;
  border-width: 11px;
  margin-left: -10px;
  top: -21px;
  right: 65px;
  z-index: 1;
} 

.drop-down-menu:after {
    content: "";
    position: absolute;
    right: 66px;
    top: -21px;
    width: 0;
    height: 0;
    border: solid transparent;
    border-width: 10px;
    border-bottom-color: #2B1A41;
    z-index: 0;
}

Code generated from CSS Arrow Please helped me a lot when I was first figuring out how to do this right.

Managing content for an art website

managing content as data

Content Management

Any product, experience, or artwork – anything you build – is made up of pieces. And content always sits at the center. Content is the fleshy part of media.

The other pieces include structure, style, and functionality.  These parts layout a skeleton, decorates the aesthetic, and adds usefulness. This  model translates well to modern web development. HTML defines the structure. CSS describes the style. JavaScript adds interactivity. But always, content is King.

That’s why a robust content management system (CMS) is critical. Most clients prefer to have one. It makes updates easy. WordPress is the modern choice. It’s what this blog is built on.

WordPress Website

A website I built featured the work of visual artist Ron Markman – paintings, etchings, photos. It had a lot of content. A lot of content that needed massaging. As you may have guessed, I chose WordPress to manage it. I choose the HTML5 Blank WordPress Theme as our starting point.

I was recommended to Ericka by a previous client. Her late relative left behind a corpus of work that needed a  new digital home. They already had a website, but needed it revamped and rebuilt from scratch.

ron markman old website

This was my proposal:

The look and feel will be modern, sleek, and adaptive. The homepage will feature a header section highlighting selected work. The website’s menu will link to the various category pages (as well as any ancillary pages). The menu, along with a footer, will persist throughout all pages to create a cohesive experience and brand identity. The website will be built responsively, adapting to all screen-sizes and devices. As discussed, select content will feature “zooming” functionality.”

art website

This was a situation where I had to be a project manager, and deliver results. Although the content itself was impressive, it was delivered as image files in various formats and different sizes. Filenames were not consistent. And the meta-data – descriptions, titles, notes – was listed is excel files that didn’t always match-up to the image’s filename. This required a lot of spot checking, and manual work. I did my best to automate as much as I could, and make things uniform.

Phases of Work

I broke the work out into four phases. This is how I described it to the client:

Layout and hierarchy

I will provide wire-frame layouts describing the essential structure, layout and hierarchy of the website overall.

Look and feel

I will finalize aesthetic details such as color palette, typography, user interface, and stylization.

Implementation

I will build and deploy the website with the content provided.

Content input

You’ll need to provide all copy, images, media, etc. before a first build of the website can be deployed. I’ll be implementing a standard content-management system that will allow you to add additional content, categories, pages, etc. Often times, content delivery can be a bottleneck for projects like this. After the finalized website is deployed live, with the initial content provided, you’ll be responsible for adding any more additionally.

Image Gallery

The UI to show each piece of art was powered by Galleria. It was out-of-the-box responsive. At first, each gallery page had so many large image files that things would crash or load very slowly. I was able to leverage the framework’s AJAX lazy loading to mitigate that issue.

Resizing Multiple Images

Resizing a batch of images can be done directly in Mac OS by selecting the files, and opening them in Preview. From the ‘Edit’ menu, I clicked ‘Select All’. Then, in the ‘Tool’ menu I found ‘Adjust Size’. Windows has a similar feature, as does other image manipulation apps.

Renaming Multiple Files

I had to make the filenames match what was listed in the meta-data spreadsheet. Here’s the command I used, in Mac OS, to truncate filenames to the first eight characters:

rename -n 's/(.{8}).*(\.jpg)$/$1$2/' *.jpg

Batch Uploading WordPress Posts

Each piece of art was a WordPress post, with a different title, meta-values, and image. Once all of the files were sized and named properly, I uploaded them to the server via sFTP. Each category of art (paintings, photos, etc.) was a folder. I created a temporary database table that matched the columns from the meta-data spreadsheet I was given.

CREATE TABLE `content` (
  `content_id` int,
  `title` varchar(250) NOT NULL,
  `medium` varchar(250) NOT NULL,
  `category_id` varchar(250) NOT NULL,
  `size` varchar(250) NOT NULL,
  `date` varchar(250) NOT NULL,
  `filename` varchar(100) NOT NULL,
  `processed` int
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
COMMIT;

I wrote a PHP script that would loop through all records, and create a new post for each. I had to make sure to include core WordPress functionality,  so that I would be able to use the wp_insert_post() method.

require_once('/var/www/html/wp-load.php');

Once I connected to the database, I queried my temporary table, excluding any records that have been marked as already uploaded:

$query = "SELECT * FROM `content` where `processed` != 1"; 
$result = mysqli_query($mysql_link, $query);

While looping through each record, I would look up the WordPress category ID and slug based on the provided category name. This would allow my code to assign the post to the correct category, and to know which folder the image file was in. Once the post is inserted, I take that post ID and assign meta-values. At the end of the loop, I mark this record as processed.

while ($row = mysqli_fetch_assoc($result)) {

    $category = $row['category'];
    $content_id = $row['content_id'];
    $term_id = "";
    $slug = "";
    $category_query = $mysqli->prepare("SELECT * FROM `wp_terms` where name = :name");
    $category_query->bind_param(array(':name' => $category));
    $category_result = $category_query->execute();
    if (mysqli_num_rows($category_result) > 0) {
        while($cat_row = mysqli_fetch_assoc($category_result)) {
           $term_id = $cat_row['term_id'];
           $slug = $cat_row['slug'];
        }
    }
    $post_id = wp_insert_post(array(
        'post_status' => 'publish',
        'post_title' => $row['title'],
        'post_content' => " ",
        'post_category' => $term_id
        
    ));
    
    if ($post_id) { 
        //meta-values
        add_post_meta($post_id, 'medium', $row['medium']);
        add_post_meta($post_id, 'size', $row['size']);
        add_post_meta($post_id, 'date', $row['date']);
        $img = $slug . $row['image'];
        add_post_meta($post_id, 'image_file', $img);
    }

    $update = $mysqli->prepare("UPDATE `content` SET processed = 1 where content_id = :content_id");
    $update->bind_param(array(':content_id' => $content_id));
    $update = $category_query->execute(); 
}

Managing clients, and their content, can be the most challenging  part of web development. Using the right software for the job makes it easier. So does having a toolbox of techniques, and being clever.

Managing server operations

This website was hosted on AWS. It used EC2. At first, the instance size we selected was too small and led to repeated website crashes. That experience led me to coming up with a hacky work-around for restarting the server when it crashed – read about it here.

Bootstrap Website for a Book Author

A vendor (video producer) to the company I worked for, who had is office on the same floor as us, mentioned in the hall way that he had a friend who needed a website. His friend was an author who just had a book published by Simon and Schuster. Joshua Horwitz released “War of the Whales” in 2014. I built his website from scratch using Bootstrap CSS and HTML5 boilerplate. It’s responsively designed, so it adjusts for mobile devices.

I even implemented a custom CMS mechanism, powered by TinyMCE, that was super light weight. It allowed him to update a few pieces of small content through out the site. It used basic authentication, and wrote to a MySQL database.

<script type="text/javascript">
tinymce.init({
forced_root_block : false,
   force_br_newlines : true,
   force_p_newlines : false,
    selector: "textarea",
	  plugins: [
         "advlist autolink link image lists charmap print preview hr anchor pagebreak spellchecker",
         "searchreplace wordcount visualblocks visualchars code fullscreen insertdatetime media nonbreaking",
         "save table contextmenu directionality emoticons template paste textcolor"
   ]
 });
</script>

I used some cool visual effects to add animation and make it feel like an immersive experience. The design process took many iterations, but we got it to a place that made sense for the project. The marquee jQuery plugin used the following code:

$('.marquee')
    .bind('beforeStarting', function(){
        
    })
    .bind('finished', function(){
       $('.marquee').marquee("destroy");
	   $(".marquee").css("overflow", "scroll")
    })
   .marquee({
	//speed in milliseconds of the marquee
	duration: 7000,
	//gap in pixels between the tickers
	gap: 0,
	//time in milliseconds before the marquee will start animating
	delayBeforeStart: 0,
	//'left' or 'right'
	direction: 'up',
	//true or false - should the marquee be duplicated to show an effect of continues flow
	
	//pauseOnHover: true
})

Project proposal

Looking back at the original agreement, this is what be planned before the project began:

I will provide two initial design direction samples. You can choose either direction, request changes, and/or combine elements from each sample. Prior to this step, you can send me examples of what you would like your website’s look-and-feel to be similar to, as well as any other specific requests regarding functionality, style, and layout. Following this, we can go through up to two more rounds of revisions regarding the style, layout, and functionality of your website. You will provide any information, text, and images (photos, logo, etc.) that need to be displayed on this website. Any stock images that we may choose to purchase for this website will cost extra.”

It was a fixed price agreement, but I added this paragraph to our documentation:

I know from plenty of experience that fixed-price agreements often limit you to your first idea about how something should look, or how it might work. I don’t want to limit either your options or your opportunities to change your mind. If you do want to change your mind, add extra sections or content or even add new functionality, that won’t be a problem. You will be charged an hourly rate.”
